The Symposium on the Photoelastic Effect and its Applications sponsored by IUTAM with the cooperation of the Permanent Committee for Stress Analy- sis and the Society for Experimental Stress Analysis was convened at IBM Ed- ucational Center, Ottignies, Belgium, September 9-14, 1973. The subject of the Symposium was the study of the interaction of matter with light in a broad sense. More specifically three main subjects were proposed: (1) Classical and advanced photoelasticity (2) Rheooptics and (3) Theoretical mechanics of a continuum in interaction with the electro-mag- netic field. For a...

Until recently there was no uniform stability theory. Different approaches to stability problems had been developed in the different branches of mechanics. In the field of elasticity, it was mainly the so called static method and energy method which were used, while in the field of dynamics it was the kinetic method, which found its perfect expression in the theory of Liapunov. During the last few decades there has been a rapid development in the general theory of stability, stimulated, for example, by the investigations of H. ZIEGLER on elastic systems subject to non-conservative loads, and...

The first IUTAM Symposium on Creep in Structures was held in Stanford, Cal. 1960 (Proceedings, ed. N. J. HOFF, Springer-Verlag 1962). That meeting reflected an intense research activity in the field of structural creep, and many important results were pre sented. In spite of this progress design rules for high temperature equipment are still often inadequate. Design against creep deformation and creep rupture is all too often based only oli experience and intuition. With technological processes moving into ever higher temperature regions the effects of creep must be given steadily increasing...

The International Union of Theoretical and Applied Mechanics (IUTAM) decided in 1992 to sponsor the fourth Symposium on Laminar-Turbulent Transition, Sendai/Japan, 1994. The objectives of the present Symposium were to deepen the fundamental knowledge of stability and laminar turbulent transition in three-dimensional and compressible flows and to contribute to recent developing technologies in the field. This Symposium followed the three previous IUTAM-Symposia (Stuttgart 1979, Novosibirsk 1984 and Toulouse 1989). The Scientific Committee selected two keynote lectures and 62 technical papers....

Structural optimization, a broad interdisciplinary field, requires skillful combining of mathematical and mechanical knowledge with engineering. It is both intellectually attractive and technologically rewarding. The Symposium on Optimization in Structural Design was the second IUTAM Symposium in Poland. Fifteen years have elapsed since the Symposium on Nonhomogeneity in Elasticity and Plasticity, presided by Professor Olszak, was held in Warsaw. These fifteen years mean a lot for mechanics in Poland. Continuing the tradition of Professor Maksymilian Tytus Huber's research, considerable...

The first Symposium Transsonicum took pl.ace 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 partici pants 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 desirabl.e for such a symposium. Participants came from aU over the worl.d and...

The International Union of Theoretical and Applied Mechanics (IUTAM) which is the head organisation of most of the existing national and international societies of mechanics, decided to sponsor a Symposium on METAL FORMING PLASTICITY. It was held near Munich (Federal Republic of Germany) between August 28 and September 3, 1978, in the "Evange- lische Academy" in the Castle of Tutzing which is situ- ated in a park at Lake Starnberg overlooking the Alps. The subjects of the Symposium were basic aspects of the theoretical and experimental mechanics of metal form- ing processes rather than...

The Symposium on "The Mechanics of Sound Generation in FLows" th st was held in Gottingen, Germany, 28 - 31 August 1979, at the joint initiative of the International Union of Theoretical and Applied Mechanics (IUTAM), the International Commission on Acoustics (ICA) and the American Institute of Aeronautics and Astronautics (AIAA). From the whole field of flow-acoustics the Symposium concen trated on prob lems of sound generation, while sound propagation and the creation of flows by sound were left in the ba- ground. 82 delegates from 12 countries attended the Symposium. 38 papers were given 5...

In the programme of the symposium was written: "The International Union of Theoretical and Applied Me- chanics has taken the initiative to organize the sympo- sium. As the name of IUTAM implies, the organization brings forward achievements within the field of theore- tical mechanics for application in science and engineer- ing. According to the rules of IUTAM that only invited persons can attend, all lecturers and participants have been ap- pOinted by the members of the scientific committee. To facilitate contact among the attending persons, it has been decided to restrict the total number to...
