INTERNATIONAL UNION OP THEORETICAL AND APPLIED MECHANICS
Reports of Symposia held In 1975
by eight scientific sessions. These sessions were grouped according to the
different types of vehicles (ranging from the scooter to the magnetically levitated
train) . The sessions were chaired by H. B. Pacejka (Delft) , P. N . Joubert
(Melbourne), H. K. Sachs (Detroit), P. Michelberger (Budapest), A. H.
Wickens (Derby, UK), H. C. A. v. Eldik Thieme ( Delft) , D. H . Weir

A local organizing committee (C. Bogerman, C. P. Keizer, P. Lemaire,
H. B. Pacejka, and A. R. Savkoor, chairman) was responsible for the day-to-day
planning of the meeting and for the social activities. Not in the last place owing
to th is committee, we may look back upon a very successful and enjoyable symposium.
We appreciate the contributions made by the following organizations in the
Netherlands: SKF-Research, DAF-Volvo, NS (Dutch Railways), ANWB
(Dutch Automobile Association) , Kivi (Royal Institute of Engineers, Automobile Division), Philips, NLR (National Aero-Space Laboratories) and IW-
The JUTAM Symposium on the Dynamics of Vehicles on Roads and on
Railway Tracks was held at the Delft University of Technology, and was
organized by the Department of Mechanical Engineering.
The following scientists were appointed by the Bureau of IUTAM to serve
as member of the Scientific Committee: M. Apetaur (Prague), G. Brunschwig
(Paris), J. R. Ellis (Cranfield, UK), M. Mitschke (Braunschweig), H. B.
Pacejka (Delft), A. D. de Pater (Delft), L. Segel (Ann Arbor, USA),
M. F. Verigo (Moscow) , A. Watari (Tokyo) , A. H. Wickens (Derby, UK).
A total number of 32 papers were presented. Besides, six state-of-the-art
papers were made available in printed form only (published in Vehicle System
Dynamics, Vol. 5, No.'s 1-2). A special report accounts for the discussions on
the orally presented papers and for the informal contributions to the Symposium
(six prepared short papers) .
Of the 32 orally presented papers and the 6 state of the art papers, 1 came
from Austria, 2 from Australia, 1 from Canada, 3 from Czechoslovakia, 2 from
France, 5 from Germany, 1 from India, 2 from Italy, 2 from Japan, 4 from
the Netherlands, 1 from Sweden, 8 from the United Kingdom, and 6 from
the United States of America. Participants, numbered about 80, came from 15
countries (besides the countries mentioned above, also from Israel and Hungary,
cf. App. I, List of participants). They were invited on behalf of the Scientific
Committee.
Monday afternoon
The Symposium had as its theme: the dynamics of the vehicle-road system.
The scope of the subjects has been restricted mainly to those problems where
the contact or guiding forces, acting between vehicle and road or guiding system,
are of primary importance. Attention was given to the presentation of new
methods and techniques which are useful in tackling vehicle dynamics problems.
The topics discussed dealt mainly with: lateral dynamics, stability and control analysis, vehicle ride on rigid and elastic supports. These aspects were covered
R. E. Roberson (USA): "Treatment of multiple contacts with the way in
dynamic simulation of multibody vehicular systems".
A. D. de Pater (Netherlands): " The longitudinal vibrations of long trains composed of identical cars, caused by braking forces".
H. H. Richardson and L. M. Sweet (USA): "Pitch-heave dynamics of tracked

is a useful tool in arriving at important biological conclusions. Professor Dubois
discussed
structural limitations involved in the inability of cell and capillary
walls to withstand large transmural pressures, and indicated how the body has
been adapted to overcome such problems.
On Monday evening there was an informal discussion on dimensional
ana!ysis,
by Professor Newman. He outlined the formal approach to the
subJect, Wtth reference to fluid mechanical examples, and then the discussion
centred on how far such techniques can be applied in a biological context when
the processes involved in the phenomenon of interest are not fully known.
It became dear that dimensional analysis can guide our work but should not be
applied blindly.

JOINT IUTAM/ IUPAP SYMPOSIUM ON BIODYNAMICS OF ANIMAL LOCOMOTION, University of Cambridge, Cambridge (UK), September
1 -September 5, 1975.
Co-chairmen: Prof. Sir James Lighthill, and Prof. T. Weis-Fogh, University
of Cambridge, Cambridge, UK.
58 ·participants from 14 countries (Australia, BRD, Bulgaria, Canada, DDR,
Denmark, France, Israel, Italy, Netherlands, Sweden, UK, USA, USSR).
Report:
Fifty-eight invited partiCJpants, representing thirty-eight institutions in
fifteen countries, assembled at Christ's College in time for lunch on Monday,
1st September, 1975. A list of participants and the programme of the meeting
are enclosed. Each of the three full days of the Symposium was devoted to one
of the general types of locomotion: terrestrial, aquatic and aerial. The first
afternoon and part of the last morning contained papers on the general constraints under which all locomotion must be performed, such as the potential
power of the musculature, the efficiency with which metabolic energy can be
converted into usable mechanical work, the supply of oxygen to the muscles, etc.
Indeed these constraints were constantly referred to throughout the Symposium,
and formed the main subject of the general discussion on the Friday morning.
Professor Knut Schmidt-Nielsen's opening lecture provided a stimulating
survey of past achievements in relating locomotory parameters to body size. He
showed how some allometric equations are accurate over an enormously wide
range of body size; one example is that the metabolic rate of heat production is
proportional to the 0.75 power of body mass, a relationship for which no satisfactory explanation has yet been found. On the other hand, within a single
species or family a different power of body mass may be obtained. Furthermore,
there are sometimes discontinuities in the graphs describing these relationships,
and these can often be traced to new mechanisms coming into play at the limit
of operation of the old (e.g. the development of convective respiratory
mechanisms in animals too large to achieve sufficient oxygen supply by
diffusion) . Such discontinuities, and factors limiting the size of different types
of animal, would prove to be the central theme of many of the papers at the
Symposium.
Dr. Goldspink outlined the physiological basis of muscle mechanics, and
indicated some of the factors, involving the strength of muscle fibres and the
most economical way of using them, which might limit the flapping frequency
of bird wings and fish tails, and the stride frequency of terrestrial animals.
Professor Wilkie, on the other hand, concentrated on the relationship between
metabolic power output and body mass, and showed how dimensional analysis
15
on terrestrial locomotion was introduced with great clarity
Tuesday's
by
McNetll Alexander, who described the different gaits used by
vanous . ammals, and examined the distribution of the different types of
mechamcal energy (potential, kinetic and elastic) in each case. He made a
strong plea, endorsed by many in the discussion, for the use of dimensionless
in plotting results. He showed, for example, that the speed of the
animal at the transition between walking and trotting, is an approximately
(gl) Y2
constant multiple of
g the
acceleration and 1 is limb length, and therefore this
veloaty IS an appropriate one to use in a comparison of different animals.
Professor Cavagna went into more detail on the transition from one gait to
another in different animals, and on the mechanical energy balance, while
Taylor examined the relation between metabolic power output and
gait
speed of locomotion. He showed that the power output increases
lmearly With speed for many animals, which can neither easily be explained,
nor
to basal metabolism. Dr. Bennet-Clark outlined the comparable
(vertically) jumping animals, indicating the origin of size
and range limitatiOns; Professor Corrsin subsequently provided the theoretical
background for various predictions which can be made in such a case. Professor
Currey and Dr. Prange both considered the structural limitations on locomotory
performance, the former in animals with bony skeletons, and the latter in
arthropods. From Currey's talk it became clear that skeletons have been
".designed" both to avoid catastrophic failure (buckling or breaking) in normal
and to reduce inefficiency in locomotion; the "optimum" skeleton
strikes a.
between these two criteria. Prange showed how the scaling
charactensttcs for hollow arthropod legs differs from that in bones, and that
different families (spiders and cockroaches) have different characteristics.

.
On Wednesday evening we were treated to a show of ftlms on fltght, to
prepare us for the following day's discussion of aerial locomotion. Dr. Rlippell
br
17
showed us some beautiful films depicting the different flight mechanisms and
wing characteristics of birds from many families, and included observations on
hovering Terns (probably near the upper size range for sustained hovering)
and on diving Boobies. Dr. Ulla Norberg then showed examples of bats in
flight, and was followed by Dr. Ake Norberg whose film illustrated the complicated wing motions used by a dragonfly, which hovers with its body horizontal. Professor Weis-Fogh's film illustrated "normal" hovering flight (body
vertical) and the now famous "clap-and-fling" mechanism used both by very
small insects and by butterflies on take off. Finally Professor Corrsin showed
some amusing shots of the "Jesus lizard" which runs on the water, keeping up
not by surface tension but by vigorous leg action.
Professor Lighthill's introductory survey on Thursday of the mechanics and
scaling of animal flight was another tour de force. All aspects of flight were
examined: fast forward flight, in which weight support is easy and the wings
must produce thrust; slow forward flight, in which the wing motions must
generate lift and thrust together; and hovering, in which weight support is all
important. He also covered soaring, including dynamic soaring, as of an
Albatross, in which energy is extracted from the wind shear. He was followed
by Professor Weis-Fogh who gave a comprehensive list of the factors limiting
hovering flight (especially of insects), including, as usual, metabolic, muscular,
elastic, and fluid dynamic. In particular he showed that three different relations
between wing-beat frequency and body length are obtained in different groups
of insects, and he examined the consequences of these relations. Dr. Kokshaysky
examined various scaling relations obtained from observations of bird flight,
and reiterated the important point that the exponent b in an allometric relation,
e.g.
wing-area a: (mass)b
may vary greatly between one species or family and another, although examination of the whole size range, involving many species, indicates a uniform value.
Mr. Rayner then outlined a brief analysis of the advantages to smaller birds to
be obtained by intermittent (bounding) flight. The morning ended with another
film, shown by Professor Wilkie, of a successful experiment in man-powered
flight.
The first two papers of the afternoon were concerned with detailed flight
mechanisms. Professor Newman described model experiments performed to
elucidate the aerodynamic advantages of the curious structure of a dragonfly
wing, and concluded that it had the effect of inhibiting boundary layer separa·
tion so that the animal can fl y at increased angles of attack without stall.
Dr. Oehme described a theoretical analysis of the aerodynamic effect of primary
feather separation. He concluded that their role is not that of reducing induced
drag but rather of increasing the lift coefficient (a view put forward by Dr.
Kokshaysky). Dr. Tucker returned to the theme of the relationship between
cost of transport and body mass, and, on the basis of his own and other data,
18
REPORT 197)
made predictions of size limitations on migrating birds. He also showed how all
reasonable considerations indicate that a pteranodon with a 15 m wing-span
could not fly; those who have suggested the possibility probably made an unjustifiable extrapolation of fossil data on bone lengths. Dr. Schaefer then
summarised an enormous amount of his own and Col. Meinertzhagen's data, to
achieve a number of scaling laws for sustained avian flight, most of which can
be closely correlated with his modified theory of bird flight, as long as the
correct quantities are chosen for scaling.
On Friday morning Dr. Vogel provided some light relief by describing a
number of interesting organisms which exploit velocity gradients in the external
medium to induce motions through or past them. Then Professor Hughes gave
a very interesting account of the scaling of respiratory function in fish and
amphibians. Once more we were made to
how important the physiological constraints on locomotion are.
Throughout the Symposium the discussions on the individual papers were
extremely stimulating, and produced a number of new ideas. This was particularly true of the final general discussion, which concentrated for the most
part, once more, on the cost of transport, and the metabolic power available for
locomotion. Professor Weis-Fogh, leading the discussion, made an estimate of
the optimum properties a muscle might have, and showed how the power
available would depend on the mode of action of muscle fibres and on the
chemical power available in them. Others suggested that "design" limitations
on locomotory ability would come from the problems of arranging for fuel
supply to the muscles as well as that of converting fuel into energy by the
muscles. Biochemical constraints were generally discussed. The problems of
nomenclature and notation to be used by workers in animal locomotion in
general, and in the proceedings of this Symposium in particular, were also
discussed. It was agreed that as much uniformity as possible should be encouraged, and that the editor should be given the freedom to modify papers
accordingly.
The main achievement of the Symposium was to bring together experts in
several fields (Zoology, Physiology, Engineering, Mathematics) who talked to
each other, in language everyone could understand, about animal locomotion.
As a result, we now have a clear idea of the general factors governing the
relationship between locomotion and body size, and are keenly aware of those
areas which we do not properly understand. The Symposium will stimulate much
new research both in the participants and in those who read the Proceedings
when they are published by Academic Press (to appear in 1976, we hope).

SECOND IUTAM SYMPOSIUM TRANSSONICUM, Gottingen (BRD),
September 8- September 13, 1975.
Chairman: Prof. K. Oswatitsch, Inst. fiir Stromungslehre,Technische Hochschule Wien, Karlsplatz 13, Wien, Austria.

Czechoslovakia, France, Germany, Italy, Japan, Netherlands, Norway, Poland,

Report:
The first Symposium Transsonicum took place in Aachen thirteen years ago
during a period of decreasing governmental and industrial support for transonic
flow research. Since then, there has been a strong revival in interest in transonic
flow research so that the number of participants at the second symposium
remained about the same as at the first even in spite of tight financial means
and limited governmental support. During both meetings the number of participants reached the upper limit of the number desirable for such a symposium.
Participants came from all over the world and there was a well balanced
distribution of participants from all countries interested in transonic flow
research. The discussions - mostly conducted in English - were stimulating
and there was a great deal of interest in the lectures as was shown by the good
attendance even during the last session on Saturday morning.
Despite some objections as to the number of lectures, the same division
as for the first symposium proved very successful. It was possible to avoid
parallel sessions and a group excursion on Wednesday afternoon gave diversion
plus an excellent opportunity for added stimulating discussions. Unfortunately
it is not possible any more to publish the contributions in the same manner as
fo r the first symposium. Because of the increasing number of publications it
was necessary to limit the size of the proceedings and to prescribe a page limit
for each contribution. So the authors had to be asked to confine their contributions to a certain size, which perhaps is not always favorable to scientific
representation. In spite of these restrictions every author has done his best to
make the proceedings a success. The proceedings shall appear in February 1976,
The distribution of the lectures over the different sessions was not as
satisfactory as it should have been. Not because too much has been done in one
area, but because there is a shortage of manpower in some other areas. The lack
of lectures on unsteady flow can be attributed to the severe difficulties in this
area, especially to the experimental difficulties. In the session on viscous flow
there were only five lectures, all of them of a very high standard. But some
supporting experimental results mentioned in the latter session were based on
experiments conducted thirty years ago ( !) . Research on cascade flow is still in
the developmental phase. In contrast, tremendous progress has been achieved
in numerical methods since the first symposium. There especially the plane
potential flow is well developed and some fine results for three dimensional
flow are also cited. Now the calculation of plane supercritical flow with and
without shock waves is only a matter of effort. Of course this progress is
closely connected to the improvement of computers.
Much research remains to be done in transonic flow. Not only must the
fundamental questions of transonic flow be investigated more intensively, but
also methods of applications must be developed further. In basic research, for
instance, there is much need for a theoretical model of buffeting, whereas in
26
REPORT t9n
applications simple and general methods for computation would be highly
desirable. This can only be done with the help of an adequate number of
scientists engaged intensively in these topics. Partly, the deficiency in research
is caused by a misguided research policy, especially by the decreasing governmental support.
The main work in the preparation and organization of the symposium was
done by the following members of the scientific committee: S. B. Berndt (vicechairman, Sweden), H. H. Pearcy, UK and of the acting organizer in Gottingen,
D. Rues.
D. Rues was also responsible for the edition of the proceedings and made
the appearance possible after such a short time.
The proceedings, containing all lectures of the symposium, are published
by the Springer-Verlag, Berlin.
The symposium was supported by the following organizations: Deutsche
Forschungsgemeinschaft, Deutsche Forschungs- und Versuchsanstalt fiir Luftund Raumfahrt, Land Niedersachsen, European Office of Aerospace Research
and Development, European Research Office, US Army, Messerschmitt-BolkowBlohm GmbH, Vereinigte Flugtechnische Werke- Fokker, Motoren- und

Report
on
the activities of the Congress Committee during 1975
As already mentioned in the IUTAM Report 1974, during the forthcoming
14th International Congress of Theoretical and Applied Mechanics (Delft,
NL, 30 August - 4 September 1976) prepared discussions of the sectional
lectures will take place. The Executive Corrunittee of the Congress Committee
decided to invite two co-chairmen for each sectional lecture who should divide
among themselves the task of chairing the lecture and the corresponding discussion; both co-chairmen should present prepared remarks on the lecture at
the opening of the discussion. In order to find suitable co-chairmen the national
organizations adhering to IUTAM and the individual members of the Congress
Committee were asked by me in May 1975 to submit suggestions. Although my
request was accompanied by a list of the 16 invited sectional lectures, which
were already fixed at that time, the response to this request was disappointingly
meagre.
At a joint meeting in Delft on 24/ 25 October 1975 the Executive Committee
and the Local Preparatory Committee of the 14th Congress drew up a list of
possible co-chairmen for the 16 invited sectional lectures. Based on this list
I sent out invitations. At the time of writing of this report the co-chairmen
for all 16 lectures were determined. Additional sectional lectures will be selected
from contributed papers by an International Papers Corrunittee, and co-chairmen
for these lectures will be invited on short notice. The Executive Committee hopes
very much that the prepared discussion sessions as well as the open discussion
sessions for the discussion of contributed papers, both new ventures for our
congresses, will prove effective means of stimulating scientific exchange.
At the joint meeting mentioned above further details of scope and arrangement of the scientific program of the 14th Congress were settled. Besides five
general lectures and thirty sectional lectures about 240 contributed papers can
be presented. A second and final announcement of the congress was drawn up,
containing details of the scientific and social program, the registration procedure
etc. This announcement was published and distributed at the end of the year.
Moreover, the final time table for the pre-selection of contributed papers by a
number of national committees and for the final selection by the International
Papers Committee was fixed.
The Executive Committee is confident that the energetic and effective work
of the Local Preparatory Committee will ensure a successful 14th Congress.

REPORT 191)
Report
on
relations with ICSU
In the meeting of the General Asembly of IUTAM at Udine on 10-11
September 1974 is was obviously impossible to report on the meetings of the
General Committee and the General Assembly of ICSU, held at Ankara and
Istanbul later in the same month. The present report will deal with those items
in these meetings, and in the meeting of the ICSU General Committee in Schlosz
Laxenburg near Vienna 19-20 September 1975, which are of more of less
direct significance for JUTAM.
1. Much to the surprise of the Union members of the ICSU General Committee
at Ankara it was announced that the categorisation of Unions for the basic
allocations from the UNESCO subvention had been changed again in the
preceding meeting of the Executive Board, at the recommendation of the
Standing Finance Committee. Several Union members, including the IUTAM
representative, expressed deep concern at this unexcepted, and in several
cases unfavourable change, in the case of IUTAM a move to category IV
with a basic allocation of $ 4.000. Decisions of the Executive Board on
financial matters are, of course, open to revision by the General Assembly
of ICSU, but inadequate information was available to members of the
General Committee and the General Assembly to take such action in a
responsible way. It was agreed, however, that the Standing Finance Committee and the Treasurer of ICSU would prepare surveys on the financial
position of the various Unions, their activities, and their incomes and
.expenditures over the five-year period 1970-1974. Such surveys would
provide a sounder basis for understanding of the background of decisions
by the Executive Board.
The surveys in question were provided in the report by the Treasurer
of ICSU for the period January - August 1975. Copies of the relevant
pages 16 - 19 were distributed to all members of the IUTAM Bureau,
and a complete copy of this report was sent to the Treasurer of IUTAM.
These surveys indicate that IUTAM is in a relative favourable financial
situation, that it receives a relatively large percentage of its total income
from the UNESCO subvention, and that it spends a larger portion of its
total income on scientific activities than any other Union. The last circumstance weighs heavily in IUTAM's favour when it applies for additional
grants, provided their purpose is clearly specified, but the other aspects do
not facilitate a realisation of IUTAM's claim to a place in a higher category
of basic allocations. The additional grant allocated to IUTAM for 1976 was
indeed $ 4.000, bringing the total allocation to $ 8.000.
The Standing Finance Committee has expressed its basic philosophy,
39
adopted also by the Executive Board and not contested by the General
Committee, in the following terms. The UNESCO subvention is intended
for scientific purposes, and grants to be made over the basic allocation
should be based on a specific purpose to be described clearly by the Union
in question in its application. An additional grant shall not exceed the basic
allocation. If the additional grants become permanently of considerable size,
a change in the categorisation will be considered.
2. In the past the General Assembly and the General Committee of ICSU have
always spent much time for the presentation of the reports by the various
Unions and other ICSU bodies on their activities. In spite of repeated
requests for less administrative detail and more substantial scientific information in these reports, few members of the ICSU family have been
able to submit reports of more scientific interest. In the meetings at Istanbul
and Schlosz Laxenburg it was agreed to have the reports of a number of
more or less related ICSU bodies presented collectively by rapporteurs who
are charged with the task to highlight the aspects of more general interest
in these reports. The principal rapporteurs at Schlosz Laxenburg, Prof.
de Jager for the earth and space sciences, Professor Keynes for the biosciences, and Professor Koiter for the physical sciences will also be invited
to a meeting of the Executive Board in May 1976 for a discussion of
priorities in the scientific programs of ICSU. Little progress has so far
been achieved in this intricate and neettling problem of priorities.
3. The President of the Committee on Science and Technology in Developing
Countries (COSTED) announced that COSTED is prepared to contribute
to grants to young scientists (under 35 years of age) from developing
countries, in order to supplement grants from the Unions for their participation in scientific meetings. Since the meeting in Schlosz Laxenburg
COSTED has already agreed to give such additional support in connection
with the 14th IUTAM Congress in Delft.
4. The General Assembly in Istanbul and the General Committee in its meeting
at Schlosz Laxenburg endorsed the continued efforts by the President and
Executive Board of ICSU to achieve the participation of scientists in the
People's Republic of China in all members of the ICSU family, without
prejudice to the participation of scientists from any other territory.
5. In its meeting at Schlosz Laxenburg the President of ICSU drew attention
of the General Committee to the fact that the free circulation of scientists
(granting of entry visas to all bona fide participants in scientific meetings
of any member of the ICSU family) encounters new difficulties, in particular in certain African and Asian countries. All Unions and other ICSU
bodies are urged to ensure the free circulation of scientists in their meetings
and to report any infringement to the ICSU Committee on the Free Circulation of Scientists.
40
REPORT 1975
6. The Executive Board raised the question of automatic ratification of ICSU
resolutions by member Unions in the meeting of the General Committee in
Schlosz Laxenburg. It was generally agreed that as much unity as is possible
should be attempted in ratifying and applying resolutions of ICSU with
reference to such general topics of policy as the free circulation of scientists
and the universality of ICSU and all its members. Several Unions, including
IUTAM, however expressed their hesitation to endorse without question any
ICSU resolution of this type no matter how it is phrased. It was suggested
that such general resolutions should be submitted to the approval of the
Unions, if a uniform adoption is desired. This matter will be raised again
at the next meetings of the General Committee and the General Assembly.
7. The next meeting of the General Committee is on October 9, 1976 in
Washington. It will be followed by a further meeting on October 16,
after the General Asseml<>ly's meetings October 10- 15. The successor to

Description of existing or planned data collection and publication activities.
Machine techniques for storage retrieval and dissemination of numerical
data.
Users of data as well as those involved in data compilation, data evaluation
and data handling are invited to submit papers on subjects within the scope of
the conference. Further information to be obtained from CODATA Secretariat,
the address of which is given below.
Whereas much of the activity within CODATA has so far centered on
fundamental constants in Thermodynamics, Chemistry and Crystallography
attention is now being focussed on other sciences, such as Biosciences and
Geosciences. Consideration of joint action with the World Federation of
Engineering Organisations Committee on Engineering information is still under
consideration.
In addition to the documents mentioned above, I think that an excellent
publication ICSU/ CODATA, 32 pp, issued 1976 by CODATA Secretariat,
51 Boulde Montmorency, 75016 Paris, France and presumably obtainable from
them, would be particularly useful for any member of JUTAM, wishing more
complete information about CODATA activities.

de COSPAR (1975)
La 18eme Reunion pleniere de COSPAR s'est tenue a VARNA. Quant a
son objet exclusif de promotion des echanges de renseignements et de vues,
sur les sujets scientifiques de la Recherche Spatiale, en vue d'y favoriser le
developement de la cooperation scientifique a la fois internationale et interdisciplinaire, cette reunion de 1975 a connu un
d'affluence et d'interet
entierement comparable acelui qui a marque les reunions analogues et annuelles
de ce Comite depuis 1960. L'organisation materielle etait parfaite et le site
particulierement agreable.
Parmi Ies sujets d'utiles discussions les plus importants, je citerai !'interpretation des resultats acquis concernant, outre la Lune, les planetes Venus et
Mars, !'application des techniques de la recherche spatiale a !'observation et a
la surveillance des ressources et de 1' ecologie terrestres, les problemes nouveaux
concernant les relations entre le Solei! et notre planete, les problemes cosmologiques souleves par !'exploration de l'Univers au moyen des rayons X et

REPORT 19D
D'un point de vue interessant plus particulierement IUTAM, je crois que
les trois sujets de cooperation pour notre Union, tant avec COSPAR qu'avec
d'autres Unions participantes (IAU, IUGG, notamment), sont les suivants,
par ordre decroissant d'interet a mon avis:
The relationship between COSTED and the various ICSU Unions was considered during the meeting of COSTED 15-17 December 1975 in Nairobi,
Kenya, attended also by representatives of IUBS, IUGG, IUPAB and IUTAM.
The need was stressed for an increased interest among the Unions for tackling
the problems of the developing countries. IUTAM suggested that COSTED
should help in establishing suitable channels of communication with the
developing countries.

laquelle les effets electriques, magnetiques, physico-chimiques et radiatifs
sont a considerer simultanement en vue de ne negligee certains d'entre eux

continuer a
de nombreux Mecaniciens.
En achevant ce rapport, je tiens a remercier notre Union de la confiance
qu'elle m'a accordee depuis 1958 pour la representee a COSPAR, ce qui m'a
permis d'assumer la presidence de ce Comite de 1962 a 1972 . Persuade qu'il
convient de transmettre cette charge et cette confiance a un autre Collegue,

COST ED
The programme of COSTED includes the award of a number of travel
fellowships supported by UNESCO. During 1975, decision was taken by
COSTED to grant $ 2000 to help participants from developing countries to
attend the 14th International Congress of Theoretical and Applied Mechanics
in Delft 1976.
The first meeting in the series "Resources and Environment: The Role of
Science Teaching" was completed in August 1975 in Accra, Ghana, where
emphasis was laid on Soil and Water.

International Commission on Acoustics
During 1975, the International Commission on Acoustics met once, in
Rome on 19th and 20th May. The question of the status of the Commission had
been put to national adhering organisations but a majority of those had expressed themselves as being averse to a change. Accordingly, it was decided to
postpone any further discussion of a change in the status of the Commission.
In the meantime, preliminary plans were made for the 9th International Congress on Acoustics, to be held in Madrid in July 1977 on the theme "Planning
the Acoustic Environment" . It was noted that Satellite Symposia would be
arranged to take place in Barcelona and Seville consecutively with the Congress.
l ater in 1975, the International Union of Pure and Applied Physics met
and approved a new membership of the International Commission on Acoustics
for 1975-1978. The Chairman is E. A. G. Shaw (Canada), and the Secretary
is B. l. Clarkson (UK). The members are A. Barone, R. T. Beyer, J. P. E.
Bosquet, H. G. Diestel, C. G. Fant, L. Filipezynski, J. Igarashi, A. lara Saenz,
L. liamshev, and B. S. Ramakrishna.
The new Commission met in Madrid on 2nd and 3rd March, 1976, and I
attended as an Associate Member representing IUTAM. The Commission had
the honour of being received in audience by His Majesty King Juan Carlos I.
The Commission was also delighted with its cordial reception by the Vice
President of the Government of Spain, as well as with the strong interest
regarding next year's Congress shown in official circles generally. At the Commission's own meetings, substantial progress was made in planning the detailed
programme of the 1977 Congress. Also, the desirability of FASE (Federation of
Acoustical Societies of Europe) becoming affiliated to I.C.A. began to be dis-
cussed.
Shortly afterwards, I.C.A. contributed an acoustics session to the I.U.P.A.P
Conference on Physics in Industry (9th to 13th March, 1976, in Dublin).
In the meantime, as a contribution to the programme of SCOPE (the ICSU

Working Groups ( "Hearing threshold levels of isolated human populations";

to which there is agreement, differences of opinion, and a need for further
scientific research. All the ICSU Unions and Scientific Committees were requested to provide information regarding their activities which may be related
to environmental problems so that they can be included in an appropriate
manner in the report to ICSU.
Participation in the SCOPE activities has often been both interesting and
challenging. This is particularly due to the need for cooperation between the
various disciplines including physical sciences, biological sciences, mathematical
methods, and socio-economic sciences which require an interface between
quantitative and qualitative studies and often may have to be based on incompletely advanced basic research information. The participation of IUTAM
scientists in some of the environmental studies facing SCOPE would contribute
to a more effective use of modern knowledge for the benefit of mankind.

Report
on
the Scientific Committee on Problems of the Environment
During the 14th General Assembly of ICSU in Helsinki, Finland, in September 1972, it was resolved that in pursuit of one of the principal objectives
of ICSU, viz., to encourage international scientific activity for the benefit of
mankind, SCOPE should identify environmental problems of high priority
which require intensive interdisciplinary effort. Following the Stockholm Conference on the Human Environment, the UN Environment Programme (UNEP)
Secretariat was established with headquarters in Nairobi, Kenya with additional
offices in New York, USA, and Geneva, Switzerland. Data in regard to those
parts of the UN Environment Action Plan Recommendations toward the implementation of which ICSU Unions and Committees could contribute were
collected by SCOPE and submitted to UNEP. These include the possible contributions which IUTAM could make in view of its expertise in the fields
of fluid dynamics and solid mechanics. More particularly, reference was made
to the significance of fluid dynamics in atmospheric pollution, water pollution,
aerodynamic noise, and other problems in atmospheric physics and physical
oceanography.
In response to the resolution of the General Assembly of ICSU urging
SCOPE to increase its scientific activity, the development involving the newly
created UNEP and concurrent with the activity of the UNESCO program on
Man and the Biosphere (MAB), there followed a particularly active period
within SCOPE including committee meetings and workshops. These involved
seven SCOPE projects: biogeochemical cycles, human impact on renewable
natural resources, environmental aspects of human settlements, ecotoxicology,
simulation modeling, environmental monitoring, and communication of environmental information and societal assessment (reference to six of these projects
was made in the IUTAM Report 1973). A major activity of SCOPE during the
past two years has been to prepare a report to the General Assembly of ICSU,
to be held in October 1976, on environmental issues most urgently requiring
international and interdisciplinary scientific effort. SCOPE was asked to define
issues deserving attention by the scientific community and to indicate the extent

International Centre for Mechanical Sciences (CISM)
Udine (Italy)
" . .. The aims of the Centre are: to promote, on a non-profit bases, research
in the field of the .Mechanical Sciences, to favour the exchange, diffusion and
application of the most advanced knowledge in this field, to establish active
relations with similar national and international institutions, to enlist the
cooperation of highly qualified scientists and research workers of the various
countries of the world, to establish research-laboratories and libraries, to set
up courses and seminars at a high scientific level ... "
from the Statute of the " International Centre for Mechanical Sciences CISM", chap. I, art. 1.
The above aims and the international scientific collaboration are being implemented by means of:
1) the organization of courses and seminars at a high scientific and modern
level;
2) the publication of monographs and test-books relevant to the courses and of
other papers and journals;
3) the creation of such conditions that international scientific meetings in the
field of Mechanical Sciences and related disciplines of various kinds may
take place at seat of CISM, like, e.g., congresses and symposia, working
sessions, group discussions, etc.;

4) the establishment of libraries and laboratories for theoretical and experimental research activities.
The Centre operates in contact with IUTAM (International Union of
Theoretical and Applied Mechanics) and with other international and national
organizations related to Mechanics. In particular it is ready - if requested - to
help in organizing meetings and discussions of these bodies.
The programme implemented in 1975 constituted a continuation of CISM's
activities in previous years. Regular courses and seminars
and appr?ved
by the CISM Scientific and Administrative Councils, respectively, were orgamzed,
free lectures delivered and several Symposia held. The editorial activities were
continued.

were selected fo r publication in book form will, consequently, be available at
reasonable prices in scientific bookshops to interested participants and nonparticipants.
The editorial activities were, in 1975, transferred to a comfortable building,
very suitable for this purpose; this was put to the disposal of the Centre by the
" Provincia di Udine".
In 1973, an International Journal for rapid communications "Mechanics
Research Communications" (bimonthly), was created by CISM and Pergamon
Press, Oxford-New York. The Journal is supposed to play an important role
in implementing CISM's aims and activities. Contributions in Mechanics of
fluids, solids, particles and systems are acceptable. The first issue appeared in
January 1974. In 1975, 47 scientific communications on fundamental research
work or its applications (due to 65 authors), 2 " work in progress" contributions
as well as 4 CISM NEWS were published in the journal. The period between
submission and appearance in print was, on the average, about 3 months.

1. Courses and Seminars
CISM's main attention was focussed on its two Scientific Sessions, the LeviCivita Session (June 16 - July 25, 1975) and the Prandtl Session (September 3October 18, 1975) each of them comprising courses and lectures during which
many highly qualified European and extra-European scientists lectured on
modern important problems of Mechanics.
The problems treated were the following:
The Levi-Civita Session (June 16-July 25, 1975):
*Propagation of Elastic and Inelastic Waves.
Thermodynamics and Dynamics of Drops and Bubbles.
Algebraic System Theory (Symposium-Advanced School).
Fundamental Analysis Techniques for Signals and Systems.
Free Lectures.
The Prandtl Session (September 3- 0ctober 18, 1975):
*Engineering Plasticity. Metal Forming Processes.
*Nonlinear Dynamics of Elastic Bodies.
*Experimental Methods in Mechanics. Strain Measurements and Evaluation.
New Trends and Open Problems in the Information Theory.
Free Lectures.
The courses marked by an asterisk * were sponsored by UNESCO and completed by auxiliary course series and seminars of several weeks ( cf. Chap. 4).

Statutes of the International Union of Theoretical
and Applied Mechanics
PREAMBLE
In order to be more fully equipped to promote development of the science
of mechanics, the International Committee for the Congresses of Applied
Mechanics at its meeting at Paris in September 1946 decided to found a
permanent organization, called "The International Union of Theoretical and
Applied Mechanics' '.
This Union has been admitted into the International Council of Scientific
Unions by decision of the Executive Committee of this Council in 1947.
At the meetings at London in September 1948 is was decided that the
International Committee would continue to organize the Congresses of Applied
Mechanics as an independent body as in the past, and that the International
Committee would have the status of an adhering organization of the Union.
At the meetings at Munich in August-September 1964 it was decided that
the International Committee for the Congresses of Applied Mechanics would
be dissolved as an independent body with the status of an adhering organization
of the Union, and that it would be replaced by a standing Committee for International Congresses as an integral part of the organization of the Union. t
I
The objects of the International Union of Theoretical and Applied Mechanics are:
a) To form a link between persons and national or international organizations
engaged in scientific work (theoretical or experimental) in mechanics or
in related sciences;

meetings for subjects falling within the field of theoretical and applied
mechanics 1;
c) To engage in other activities meant to promote development of mechanics,
both theoretical and applied, as a branch of science.
III A 1
International organizations mainly occupied in scientific work in fields
closely related to that of the Union can be admitted by the General Assembly
as affiliated organizations of the International Union.
Each affiliated organization has the right to appoint an observer, who is
invited to take part in the General Assembly without voting rights.
The affiliated organization is obliged to keep the Bureau (section VII) of
the International Union informed about all important activities of and organizational measures taken by it. The affiliated organization will incorporate a
representative appointed by the Bureau of the International Union in its scientific council or the corresponding organ.
In organizing international scientific meetings of its own the affiliated
organization is obliged to consider carefully all measures already taken by the
International Union and it! other affiliated organizations in order to coordinate
such international scientific activities.
Affiliated organizations pay no annual dues to the International Union.
II
The active organ of the International Union of Theoretical and Applied
Mechanics is its General Assembly.
The General Assembly has power to decide all questions affecting the
Union, including alteration of the statutes. On a specified question it may
delegate this power to appropriate bodies.
The composition of the General Assembly is regulated in Article IV.

REPORT t 9n
Resolution of the General Assembly at Pallanza
(June 27, 1950)
In confirmation of the views already expressed at the General Assembly of
September 1948 when the present statutes were framed :
1. The General Assembly expects that in those countries where more than
one national organization is active in theoretical and applied mechanics, a
national coordinating committee will be formed. In general it is expected to
recognize only one adhering body in each country;
2. The General Assembly believes that a gradual transition should be made
in its composition, so that ultimately it will consist mainly of representatives of
organizations adhering to the Union with the category of elected members
reserved for exceptional and unusual cases. To this end it gives notices of its
intention to reduce the number of elected members when the terms of the
present elected members expire in 1952.
Rules of procedure 1 for the Congress Committee of IUTAM
(September 4, 1964)
1. The Congress Committee meets at least once at every Congress.
2. The Congres Committee may appoint an Executive Committee to take
all necessary actions on its behalf in the period between two successive Congresses, and to report to it at its next meeting. The Executive Committee will
consist of the president, the secretary and one or more members appointed by
the Congress Committee.
3. The actual organization of a Congress is delegated to a local Organizing
Committee, elected by the host-country or host-organization, which is also
responsible for publication of its Proceedings. The Organizing Committee will
report to the Congress Committee either during or, if it sees fit, before the
Congress which it organizes.
4. The Organizing Committee will obtain the approval of the Congress
Committee "(normally through the Executive Committee) with regard to all
matters affecting the general policy of the Congress Committee, in particular
with regard to:
4.1 the scope of the Congress;
4.2 the screening of papers for the Congress;
4.3 the selection of general lectures for the Congress;
4.4 the appointment of chairmen of sessions of the Congress.
