Short summary of scienttfic progress achieved

The subject of aerothermodynamics is playing an ever increasingly critical role in a variety of important industrial and technical problems in the design of combustors. Due to the rapid and phenomenal developments of key research tools mostly in the last two decades, in particular those of modern digital computers, laser optics, and electronics, many of the previously unthinkable, rigorous investigations in real-life flows have gradually become feasible. It was the aim of this international conference on the aerothermodynamics in combustors to being held at this point in time to provide a forum for presentation and discussion of current achievements in the area of combustion. The Symposium involved the presentation of 40 papers concerned with flow and thermodynamic characteristics of combustors, with emphasis on gas-turbine combustors and including information relevant to rocket motors, internal combustion engines and furnaces. It was


evident that the Symposium was very successful. The papers were well received, the discussions very active and the interactions inside the lecture hall were considerable. In the panel discussion, with the theme of "Status and Likely Development in Calculations and Measurements of Combusting Flows," by the leading experts and all participants has inspired a variety of research directions and topics in the field of combustion for the future.

Short summary and scientific progress achieved

The field of welding is an area which includes a large number of scientific disciplines, such as materials science, solid mechanics, thermal science, and also mechanical engineering design and production engineering. The intention of the Symposium was to cover the direct mechanical effects of welding and their influence on the in-service behaviour of welded structures. Progress in this field requires close interaction between researchers in several disciplines. This is reflected in the 28 papers presented by leading experts in the field of the Symposium. The main achievement of the Symposium was this close interaction between disciplines and also the interaction between theorists and experimentalists. These interactions led to very fruitful discussions. Due to these new scientific contacts, the exchange of ideas and results as well as the international cooperation will be enhanced in the future.

The conference brought together researchers from a broad range of backgrounds, all of whom are interested in the mechanical behavior of fluidsolid mixtures. The participants represented the disciplines of applied mathematics, applied mechanics, physics, and chemical, civil, mechanical and thermal engineering. The program allowed time for wide-ranging discussions in which differences in approach and interpretation were fully explained and appreciated. One of the most tangible measures of progress achieved was a realization that understanding interactions between particles themselves and between particles and the suspending fluid, represents the key to understanding the macroscopic mechanical behavior of such systems. There were many talks in which this understanding was elucidated, and there were many discussions of ranges of parameters over which specific interaction mechanisms were dominant. Less tangible is the considerable success achieved in effecting a viable communication among such a diverse group. There have been many conferences in the past devoted to this subject and attended by similarly diverse groups, in which effective communication was absent. This conference was very successful in this regard. Engineers and mathematicians alike came away with new insights, ideas for further work, and appreciation for large bodies of knowledge that were previously unknown to them. The invited speakers were particularity effective in laying the groundwork for success.

Wave breaking is a commonly occuring phenomenon associated with wave motion in fluids, often inducing significant effects of fundamental and technological importance. The Symposium focussed on water waves of all scales from capillary waves to ocean swell, and to broaden the framework of discussion also considered internal waves and filarnentation of vorticity interfaces. There were 45 contributions given by leading international experts included fundamental theoretical studies, wave breaking models, field and laboratory observations, and industrial and scientific consequences. Through these contributions and the extensive informal discussions the Symposium achieved its goal of establishing the current state of knowledge of wave breaking and providing a stimulus for future research.

J. Lemaitre (France) K. W. Neale (Canada) P. Perzyna (Poland) R. Wang (China), Co-chairman A. Zaoui (France)


The primary aim of the Symposium was to survey the latest advances in this challenging subject, the papers were devoted essentially to:

l. Physical theory and mathemat1cal formulation of constitutive relations for finite deformation plasticity, thermoplasticity and dynamic plasticity. As well as heterogeneity, creep, inelastic behaviour of metals based on stochastic models.

2. Mathematical description, experimental investigation and numerical simulation on micromechanics and constitutive relations of sliding polycrystals, polycrystalline composites, multiphase materials, phase transformation and shape memory alloys.

3. Mathematical analysis and experimental investigation on the effects of plastic spin, inclusion, creep damage, softening, inverse swift effect, non-proportional loading and rachetting on large plastic deformation.


Throughout the Symposium a remarkable advance on interaction and stimulation between macromechanics and micromechanics for insight into the subject was achieved. The lectures were excellent and the discussions fruitful, the importance of computation modelling and basic experimental studies are clearly emphasized. Interdisciplinary cooperation was another outstanding feature of the Symposium, Western scientists have come to know the works done by Chineses colleagues. International exchange of ideas and information were commended.

The scope of the symposium was a fundamental treatment of plasticity and viscoplasticity at finite strains. This covers the material theory with different concepts for isotropic and anisotropic hardening as well as texturing on crystalline-, meso- and continuous macroscopic levels and their comparisons. Furthermore mechanical and thermal softening, microdamage and the localization of deformations, i.e. material instabilities, were treated according to new research results based on microstructural observations and reliable experimental data. An important issue was the connection of physical understanding with the mathematical analysis of the models and the identification of material data from experimental measurements.

IUTAM Symposium on Microgravity Fluid Mechanics, 2-6 September 1991, Bremen, Germany.

Substantial progress has been made in the field of fluid mechanics under compensated gravity ( microgravity) in the last decade. The main task of this discipline has evolved tremendously. Starting out with the aim of providing assistance in describing flow problems in other microgravity sciences, microgravity t1uid mechanics has itself now become acknowledged as powerful means of research. This is especially true in the investigation of many basic fluid phenomena, which have so far been otherwise intractable because of gravity effects in earthbound research. The IUTAM Symposium on Microgravity Fluid Mechanics has provided the long-waited forum for invited speakers and scientists from a large number of countries to discuss and concretize the "state-of-the-art" in this discipline. Based on this "stocktaking", future goals for research in this field have been defined the pathways towards achieving them have been charted. The overall shape of this Symposium was determined by the main themes including: Interface phenomena (liquid bridges, thermal Marangoni effects, thermocapillary motions of drops and bubbles), thermosolutal instabilities applications in t1uid management and particle migration at fronts. This was most successfully accomplished by 61 contributions by leading experts in the corresponding fields as well as young, promising scientists. Response to the Symposium indicated a high level of personal interaction and changing of ideas between participants. The lively and thorough panel discussion definitely laid ground to further research in this important field of Fluid Mechanics. Additionally the unsolved questions concerning the relationship to other microgravity disciplines, prospects for funding microgravity research and further development with IUTAM were addressed. After discussion of the latter topic it has been decided to propose to IUTAM to include a miniSymposium on Microgravity Fluid Mechanics in their quadrennial meetings.

The IUTAM Symposium on Local Mechanics Concepts for Composite Material Systems brought together over 70 scientists and engineers from fifteen countries to consider the results reported in 34 papers at the Symposium and a companion workshop (sponsored by the NSF). The Symposium is thought to be the first attempt to comprehensively address the analytical and numerical methods and experimental data that define local stress and strain fields in fiberous composite materials, including the "systems" aspect, i.e., the constituent interactions and combined actions that control the unique properties and performance of such inhomogeneous materials. The Symposium clearly defined this technical area, presented a state of the art, and identified capabilities, limitations, and opportunities associated with the related science to technology.

The activities ofthe Congress Committee during 1991

The Congress Committee continued its work of planning for the 18th International Congress of the Theoretical and Applied Mechanics, which will be held in Haifa, Israel, 22 to 28 August 1992. No formal meetings of the Congress Committee were held during the year, but the Executive Committee met in Udine on 31 August and I September 1991, in order to confirm the final arrangements. At this meeting, the Final Announcement was approved, and this was widely circulated during November 1991. The Executive Committee gave particular consideration to problems relating to the participation of scientists from Eastern Europe and from the territory of the former Soviet Union. It was agreed that some action was essential in order to enable the participation at the Congress of at least some young scientists from these countries. It was reported that the Bureau of IUTAM had agreed to provide a special grant of$ 10 000 for this purpose. The Committee further agreed to increase the registration fee by$ 20 (to $ 360) in order to augment the fund for making grants to scientists who would otherwise have no possibility of participation. It was agreed that the International Papers Committee should consider applications at its meeting in Haifa at the end of March 1992, and draw up a list of recommendations for grants, on which the Local Organising Committee could act. Final plans have been made by the Israeli hosts for all the arrangements, scheduling, excursions, and all other details concerning the Congress. The Executive Committee looks forward to a successful Congress, and is grateful to the local organisers for all their efforts in this regard.

Relations with ICSU

The 29th meeting of the General Committee of ICSU took place in Oslo, Norway, 25-27 September 1991. The 60th meeting of the ICSU Executive Board was held in Oslo the same week. Among items discussed at length during these meetings were:

1. Consequences of the use of weapons of mass destruction

An ad hoc working group within the Executive Board had looked into the feasibility of an ICSU programme to investigate the consequences of the

62 REPORT 1991

use of biological, chemical, and nuclear weapons. On the recommendations of the ad hoc group the General Committee decided to request SCOPE to undertake a study of the environmental effects of the use of such weapons of mass destruction, in the light of SCOPE's experience in its recent study of the environmental effects of nuclear war (ENUWAR Project).

2. Admissions to ICSV

Scientific Associate Membership had been sought by four bodies, and the conditions for such membership were discussed. Arguments were brought forward for increased contact between ICSU and organisations representing engineers. The General Committee also expressed a wish that emerging new nations be represented within ICSU.

3. Science in Central and Eastern Europe

The new ICSU Committee on Science in Central and Eastern Europe (COMSCEE) held a meeting in Oslo that same week. The General Committee encouraged COMSCEE to continue its important activities in assisting the scientific communities in the countries concerned.

In recent years efforts within ICSU have been increasingly focused on large scale projects, such as The International Geosphere-Biosphere Programme (IGBP) and The Third World Academy of Sciences (TWAS). A lecturing programme has been set up within TWAS to offer high quality scientific lectures to groups in third world countries. The most recent ICSU effort on this scale is The International Decade for Natural Disaster Reduction (IDNDR). A memorandum from the Chairman of the ICSU Special Committee for IDNDR, Sir James Lighthill, presenting the objectives of \DNDR may be obtained from ICSU.

The next meeting of the General Committee will take place in Jerusalem, Israel, 5-7 November 1992.

Committee on Data for Science and Technology

CODATA celebrated its 25th Anniversary in 1991 with its usual optimistic view of the future in which all segments of the scientific community in all parts of the world will have access to the accurate and reliable data they need. Many people devote a great amount of time to help the world community advance toward this goal. Of necessity, much effort these days is going into the gigantic data problems associated with Global Change and rapidly growing areas of biological science. Yet, both the fluid and solid aspects of materials science and engineering areas that are


of interest to many workers in mechanics continue to get considerable attention.

Committee on Space Research

The 1992 World Space Congress will be held in Washington DC from 28 August to 5 September 1992. A large number of Symposia and Scientific Meetings will be held during this Congress, of which the following are of particular potential interest to IUTAM:

A.5-M Satellite Observations of the Ocean and Air-Sea Interactions with Emphasis on New Results from ERS-1.

B.7-M The Orientation of the Planet Earth as Observed by Modern Space Techniques.

C.2-S The Middle Atmosphere: Its Energetics, Chemistry and Dynamics and Coupling to Regions Above and Below

G.1-S Gravity- Dependent Phenomena in Fluid and Material Sci-ences.

P.1-M Dynamics of Satellites and Probes.

The latest Information Bulletin No. 122 of COSPAR, published in December 1992, contains full information about these and all other scheduled Symposia. The Bulletin also provides much information concerning forty-two satellites and space probes launched during the period February-June 1991. The General Assembly may like to be reminded of the origin and aims of COSPAR (Committee on Space Research): COSPAR was established by the International Council of Scientific Unions (ICSU) in October 1958 with the following primary purpose: "to provide the world scientific community with the means whereby it may exploit the possibilities of satellites and space probes of all kinds for scientific purpose, and exchange the resulting data on a cooperative basis". Each International Scientific Union federated in ICSU and desiring membership in COSPAR may appoint one delegate to COSPAR. Information Bulletins are published thrice annually.

International Commission on Acoustics

The 1991 meeting of the International Commission on Acoustics was held on 24-25 May in Amsterdam, Netherlands. It was the first meeting chaired by the Commission's new Chairman, Professor David T. Blackstock (USA). Much of the meeting's work was devoted to planning the 14th International Congress of Acoustics, to be held in Beijing, China from 3-10 September 1992. Unfortunately the previous intention to hold the Beijing Congress in the International Conference Centre has had to be abandoned on grounds of cost, and the Congress will now be held in one of the hotels. Excellent speakers have been selected for the scientific sessions; in addition to which there will be some well organized "structured sessions". Finally, planning for the 15th International Congress, to be held in Trondhcim, Norway on the University campus from 26-30 June 1995, was begun.

International Association for Vehicle System Dynamics (IAVSD)

The 12th Symposium on the Dynamics of Vehicles on Roads and Tracks was held at the Ecole Centrale de Lyon, France, in August 1991 under the Chairmanship of Dr. G. Sauvage of the Institut National de Recherche sur les Transports et leur Securite. 164 delegates from 22 countries attended. 68 papers included 6 State-of-the-Art presentations and 16 poster papers. The papers have been published by Swets and Zeitlinger, Lisse as part of, and a supplement to, Volume 20 of Vehicle System Dynamics. Following the workshop meeting in Herbertov, Czechoslovakia in September 1990 on "Applicability of Multibody Methods and Computer Codes to Problems in Vehicle System Dynamics", as described in the last IUTAM report, this theme received special attention at the Symposium. Contrary to the original intentions, work on "benchmark" problems was not complete at the time of the 12th Symposium and an interim account to the work done had to suffice. The work has continued and the final


report is now being put together. In order to specify reasonably complex modelling problems without ambiguity, the greatest possible care is needed. A second workshop meeting in Herbertov is planned for June 29th to July 3rd, 1992, under the title "Research issues in automotive integrated chassis control systems". In accordance with the previous experience, it is hoped to prepare material for presentation at the 13th IA VSD Symposium, which will be held in Chengdu, P.R. China, hosted by Southwest Jiaotong University, Chairman: Professor Z. Y. Shen, 23-27 August 1993.

Statutes of International Union of Theoretical and Applied Mechanics

I "The International Union of Theoretical and Applied Mechanics" hereinafter called "the Union" is an international non-governmental scientific organization.

II The principal objectives of the Union are a) to form a link between persons and organizations engaged in scien

tific work (theoretical or experimental) in mechanics or in related sciences;

b) to organize international congresses of theoretical and applied mechanics through a standing Congress Committee (Article XII), and to organize other international meetings for subjects falling within the field of theoretical and applied mechanics;

c) to engage in other activities meant to promote development of mechanics, both theoretical and applied, as a branch of science.

III The highest authority of the Union is its General Assembly. The General Assembly has the power to decide all questions affecting the Union, including alterations of the Statutes. On specified questions it may delegate its power to appropriate bodies. The composition of the General Assembly is regulated in Article VI. Meeting of the General Assembly will take place at times decided by the Bureau (Article XI) or on the request of at least 10 members of the General Assembly.

IV In all its decisions the General Assembly shall be guided by the tradition of free international scientific cooperation, developed in the International Congresses for Theoretical and Applied Mechanics. In pursuing its objectives the Union shall observe the basic policy of nondiscrimination and affirm the rights of scientists throughout the world to adhere to or to associate with international scientific activity without regard to race, religion, political philosophy, ethnic origin, citizenship, language or sex.

v In voting every member of the General Assembly shall dispose of one vote. For an alteration of the Statutes the majority required is 2/3 of the votes brought forward. For all other decisions a simple majority of the votes brought forward is required.


Any member who is unable to attend a meeting may by a letter to the Secretary General constitute another member of the General Assembly as proxy. Between meetings of the General Assembly voting may be carried out by correspondance upon proposals made by the Bureau (Article XI); in this case decisions will be valid only provided the number of persons taking part in the vote is not less than 2/3 of the total membership of the General Assembly.

VI1

The General Assembly is composed of a) representatives of the adhering organizations (Article VIII); b) members of the Bureau (Article XI); c) members elected by the General Assembly of the Union, who shall

be persons actually engaged in scientific work in mechanics or in related sciences;

d) representatives of committees and groups of scientists, if so decided by the General Assembly.

The term of an elected member shall be determined by the General Assembly at the time of the election. The term of members of the Bureau shall coincide with their term of service on the Bureau.

VII The General Assembly shall provide for an adequate representation of any group of scientists carrying out research in theoretical or applied mechanics and not represented by an adhering organization.

VIII Organizations of scientists in theoretical or applied mechanics (or unions of such organzisations) which effectively represent independent scientific activity in a country or in a definite territory can be admitted by the General Assembly as adhering organizations of the Union provided they can be listed under a name that will avoid any misunderstanding about the country or territory represented. In general only one organization from each country or territory will be admitted.

IX Each adhering organization shall have representatives in the General Assembly of the Union, and pay an annual subscription to the Union in accordance with Article XIV.

1) Adopted by the General Assembly on September 2, 1990 in Vienna (Austria)

80 REPORT 1991

X International organizations mainly occupied in fields closely related to that of the Union can be admitted by the General Assembly as affiliated organizations of the 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 Bureau of the Union (Article X) has the reciprocal right to appoint a nonvoting observer to the corresponding council or other executive body of the affiliated organization. The affiliated organization and the Union are mutually obliged to keep each other informed about all important activities of and organizational measures taken. In organizing international scientific meetings the Union and each of the affiliated organization are obliged to consider carefully all measures already taken by the Union and its affiliated organizations in order to coordinate such international scientific acitivities. Affiliated organizations pay no annual dues to the Union.

XI1

To execute the decisions of the General Assembly and to carry out work between meetings, the General Assembly elects members of a Bureau for a period of at most four years. The Bureau consists of the officers (President, the retiring President who serves as Vice-President, Secretary-General, and Treasurer) and four other persons who shall have been members of the General Assembly at some time within the four years preceding the time of election to the Bureau. The maximum continuous period of service as a member of the Bureau, other than an officer, is limited to eight years. Newly elected members of the Bureau enter into office on the date of November 1, following the General Assembly at which they were elected. The Bureau will meet at least every year. A member of the Bureau who is prevented from attending a meeting may by letter to the Secretary-General designate another member of the General Assembly as a replacement. The Secretary-General will act as a permanent center for all matters affecting the Union, including relations with adhering, affiliated and other organizations. The legal domicile of the Union shall be the place where the SecretaryGeneral lives. The Bureau is authorized to appoint Assistant-Treasurers in those countries where the Union has a bank account. The Assistant-Treasurers must be members of the General Assembly but need not to be members of the Bureau.

1) Adopted by the General Assembly on September 2, 1990 in Vienna (Austria)


The Bureau shall draft a budget for each coming year, and shall administer the finances. The Bureau shall submit an annual financial report to the General Assembly. The Vice-President shall normally fulfil the duties of the President should the President become unable to discharge them. Between meetings of the General Assembly the Bureau shall decide who shall undertake the duties of the Vice President, Secretary-General, or Treasurer should a temporary replacement be necessary.

XII The General Assembly establishes a standing Congress Committee which is responsible for the organization of International Congresses of Theoretical and Applied Mechanics at regular intervals. a) The President of the Union shall also serve as President of the Con

gress Committee. b) The members of the Congress Committee are appointed by the Gen

eral Assembly as scientists active in theoretical or applied mechanics and need not be members of the General Assembly.

c) The Congress Committee appoints a Secretary, without stated terms of office.

d) The rules of procedure of the Congress Committee shall be approved by the General Assembly.

XIII The financial means of the Union are formed by: a) the annual subscriptions of the adhering organizations; b )gifts and grants.

Resolution of the General Assembly at Pal Ianza {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 for the Congress Committee of IUTAM

l. The Congress Committee meets at least once at every Congress. 2. The Congress 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 of the Congress; 4.3 the selection of general lectures for the Congress; 4.4 the appointment of chairmen of sessions of the Congress; 4.5 the broad principles regarding financial arrangements for the Con

gress.


5. The Organizing Committee will levy a fee (the level to be recommended by the Congress Committee and approved by the Bureau) for administrative expenses of the Congress Committee, from all Congress members. This fee will be paid over to IUTAM after the Congress.

Procedure 1 for election of the Bureau of lUTAM

1. At the General Assembly, preceding the one at which the new Bureau is elected, an Electoral Committee (EC) shall be elected, consisting of the President of the Union and two to four other members of the Assembly, who are not members of the Bureau.

2. The President is Chairman of the EC.

3. Proposals by members of the General Assembly with voting rights for members of the Bureau, viz. for President, Treasurer, Secretary-General, and the other four members to be elected, must be addressed to the Chairman of the EC within a time limit set by the Committee. All proposals will be treated confidentially by the Committee.

4. Taking into account all material received the EC is charged with the duty of presenting to the General Assembly such proposals as it deems will have at least a reasonable support by the General Assembly. The EC will make sure that the candidates thus proposed are willing to accept an election. The proposals by the EC will be circulated to all members of the General Assembly during the first session of the meeting of the Assembly at which the Bureau will be elected.

5. Proposals not identical with the ones of the EC are considered to he withdrawn, unless they are sustained and supported by at least ten members of the General Assembly before its second session.

6. The General Assembly will vote on those candidates mentioned in the proposals of paragraph 4 and 5.

c) Proceedings of the International Congresses for Applied Mechanics. Until September 4, 1964 the organization of the International Congresses for Applied Mechanics was supervised by the "International Committee for the Congresses of Applied Mechanics" and for each Congress separately entrusted to a local Organizing Committee undertaking also the publication of the Proceedings. Consequently, there is no central point from which Proceedings can be ordered, and for each volume, application must be made to the publishers who took care of that particular volume. Since September 4, 1964 the same task will be fulfilled by the Standing Congress Committee of !UTAM, and local Organizing Committees to be established. The titles of the volumes and the names of the publishing firms are given below.
