The International Congress of Theoretical and Applied Mechanics held in Warsaw, Poland is the twenty first congress of a series started eighty years ago in Delft, Netherlands. The idea of congresses devoted to mechanics, can be traced back to a conference devoted to the problems of fluid mechanics in Innsbruck, 1922. It was organized by four individuals, whose names, are and will, remain very well known to next generations of scientists, C. W. Oseen, T. Levi-Civite, T. von Kármán, and L. Prandtl. This conference was so fruitful, that the organizers decided to arrange similar meetings in the future, every four years, and to extend the scope of the future meetings to include solid mechanics.

From the meetings of the Congress Committee sprang the idea of a more permanent organization to look out for the world interests in the mechanical sciences. Thus, IUTAM, the International Union of Theoretical and Applied Mechanics, was formed on September 26, 1946. In 1947 IUTAM became a member of ICSU, the International Council of Scientific Unions, itself founded in 1931. The highest authority of IUTAM is the General Assembly, with delegates from the Adhering Organizations, each of which is affiliated with a national learned society in a given country.

Map of previous ICTAM Congresses

Contemporary mechanics poses both, the fundamental problems from the area of pure science, and its strong links with modern technology. It spreads over such areas of our knowledge as oceanography, physical chemistry, biology, medicine, geophysics and astrophysics. Hence, any conclusions deduced in the framework of mechanics, are likely to have a value for other fields. We do hope that this meeting will contribute in widely spreading the knowledge in our field of interest and the advancement of mutual human understanding. James Clerk Maxwell put it in a short conclusion:

The true seat of science is not in the volume of transactions, but in the living mind, and the advancement of science consists in the direction of the men's minds into a scientific channel.

One of these channels, the 21^st International Congress of Theoretical and Applied Mechanics was invited to be held in Warsaw by the:

• Polish National Committee of IUTAM
• Institute of Fundamental Technological Research of the Polish Academy of Sciences
• Warsaw University of Technology

We hope that the Congress will stimulate the endeavours to find the solutions to some open problems of mechanics, and will pose some new questions, to be answered in future. We would like to thank all the contributors of this Congress. Your contribution of up to minute research makes the Congress a success. Welcome in Warsaw!

The scientific program consists of plenary opening and closing lectures, sectional lectures, mini-symposia, and contributed papers presented in lecture and seminar presentation sessions. These are intended to cover all aspects of mechanics. This volume contains 1417 papers, having been drawn on from the oral and the seminar presentations of the congress. Each paper consists of a printed Short Abstract and an Extended Summary recorded on an enclosed CD-ROM. Obviously, the book that has to be available at the congress is based on papers that had to be submitted over half a year ahead. Therefore, the congress itself, in many cases, may deliver more recent data and evaluative work than had been possible to allude to in the publication.

All contributed papers were peer reviewed. Recommendations had been received from Pre-selection Committees of the National Committees of the nine countries: Canada, France, Germany, Japan, PR China, Poland, Russia, UK and USA. Moreover, recommendations had been received from the Chairs responsible for the Mini-Symposia and the Pre-nominated Sessions with classifications of the papers submitted within the topics of their Symposia/Sessions. Finally, the International Papers Committee paid careful attention to the above recommendations. Accordingly, of the 2086 eligible submissions 1574 contributions were invited by the IPC for their presentation. The total number of submitted and accepted papers represents a quite substantial enhancement relative to the previous congresses, providing evidence of vitality of the contemporary mechanics.

Throughout the book and CD-ROM all papers are coded using letters and numbers denoting appropriate session code, presentation type, presenting author's ID, presentation day, time and lecture room. Following codes are used to mark sessions:

OL, CL - Opening and Closing Lectures

SL - Sectional Lectures

MS - Mini-Symposia

Pre-nominated Sessions:

FM - Fluid Mechanics

SM - Solid Mechanics

FSM - Topics involving Fluid and Solid Mechanics

Presentation types are: Plenary (I), Lecture (L) and Seminar (S)

We would like to express our thanks to our colleagues from the IUTAM Congress Committee, and from the International Papers Committee. Their advice and efforts have helped us to overcome some problems, connected, as usual, with the organization of world-wide meetings.

Special gratitude goes to the Chairs responsible for Mini-Symposiums and Pre-nominated Sessions. Their work in organizing sessions, encouraging papers submission in the area of interest, and later reviewing all papers cannot be overestimated. Smilingly, we are deeply indebted to members of the nine National Committees for their valuable contribution to the reviewing procedure.

The organization and execution of the Congress is performed by the Institute of Fundamental Technological Problems Polish Academy of Sciences and Warsaw University of Technology. The detailed work of organization is due to many persons from both institutions, personnel of PCO Mazurkas Travel as well as numerous external co-workers. Without their extremely valuable help organization of such meeting would be impossible. Thank you all so much!

Finally, we would like to express our thanks to the supporting institutions and sponsors, most of them listed below. Their support has helped us to balance finances of the congress form the first days when the ICTAM04 organizational work started in Fall 2000.
