This volume contains the proceedings of the IUTAM Symposium on Dynamical Problems for Rigid-elastic Systems and Structures held in Moscow, USSR in May 1990. This symposium brought together scientists working in the fields of multibody system dynamics and finite element systems with special emphasis to modeling, simulation, optimization and control. The scientific lectures were devoted to the following topics: - Modeling and optimization; - Dynamics of systems with elastic constraints; - Vibrations; - Multibody systems. The papers presented indicate the importance of these topics with respect...

The field of welding is an area which includes a large num- ber of scientific disciplines, such as materials science, solid mechanics, thermal science and mechanical engineering design and production engineering. The intention of the Sym- posium was to cover the direct mechanical effects of welding and their influence on the in-service behaviour of welded structures. The mechanical effects of welding is a very ap- propriate theme for an IUTAM Symposium. Progress in this field requires close interaction between researchers in se- veral disciplines. This is reflected in the topics covered....

A Symposium on Aerothermodynamics of Combustors was held at the Institute of Applied Mechanics of the National Taiwan University from 3 to 5 June 1991 and was attended by 130 delegates from eight countries. The topics of the forty formal presentations included measurements and calculations of isothermal simulations and of combusting flows with one and two phases, and with consideration of configurations ranging from simple diffusion to gas-turbine flows. The discussions inside and outside of the Symposium Hall were lively and an open forum session demonstrated the range of opinions currently...

The Symposium, held in Torino (lSI, Villa Gualino) July 1-5, 1991 is the sixth of a series of IUTAM-Symposia on the application of stochastic analysis to continuum and discrete mechanics. The previous one, held in Innsbruck (1987), was mainly concentrated on qual itative and quantitative analysis of stochastic dynamical systems as well as on bifurcation and transition to chaos of deterministic systems. This Symposium concentrated on fundamental aspects (stochastic analysis and mathe matical methods), on specific applications in various branches of mechanics, engineering and applied sciences...

The application of composite materials to engineering components has spurred a ma jor effort to analyze such materials and the structures made from them. Most researchers workin in mechanics of composite structures understand that composite materials pro vide umque advantages but also present complex and challenging problems to researchers. The complex inelastic behavior and variety of failure modes of composite structures are a result of the strength and stiffness properties of constituents and their complex interac tions. Macromechanical constitutive models based on gross composite...

The IUTAM-Symposium on "Finite Inelastic Deformations - Theory and Applications" took place from August 19 to 23, 1991, at the University of Hannover, Germany, with 75 participants from 14 countries. Scope of the symposium was a fundamental treatment of new developments in plasticity and visco-plasticity at finite strains. This covered the phenomenological material theory based on continuum mechanics as well as the treatment of microstructural phenomena detected by precise experimental datas. In a restricted number, lectures on new experi mental facilities for measuring finite strains were...

This book contains the proceedings of the IUTAM Symposium on Breaking Waves, held at the University of New South Wales in July 1991. The Symposium brought together theoretical and observational expertise, and the proceedings provide a current and comprehensive account of the present knowledge of wave breaking, including state-of-the-art reviews and exciting new results. The articles cover water wave breaking of all scales from capillary to ocean swell and include fundamental theoretical studies, wave breaking models, field and laboratory observations, shoaling waves and engineering...

The IUTAM Symposium on Nonlinear Instability of Nonparallel Flows was held at Clarkson University, Potsdam, NY 13699-5725, USA from 26 to 31 July 1993. It consisted of 9 general speeches, 35 lectures and 15 poster-seminar presentations. The papers were grouped in fairly focused sessions on boundary layers, shear flows, vortices, wakes, nonlinear waves and jets. The symposium was fol lowed by a workshop in which the subject matter discussed was sum marized and some further work for future investigation was recom mended. The highlights of the workshop will be reported elsewhere. In this book...

This symposium is the seventh of a series of IUTAM symposia dealing with probabilistic methods in mechanics. It focused on advances in the area of probabilistic mechanics with direct application to structural reliability issues. The papers selected for this volume address collectively the four components of a structural reliability problem. They are: characterization of stochastic loads, description of material properties in terms of fatigue and fracture, response determination, and quantitative assessment of the reliability of the structural system. They include Keynote Lectures by V....

The IUTAM Symposium on "Discrete Structural Optimization" was devoted to discuss optimization problems for which design va riables may not be sought among continuous sets. Optimum sizing from lists of available profiles, segmentation; as well as allocation and number of supports, sensors or actuators, are good exam ples of such problems for which design variables may be chosen only from finite sets. The above problems are having not only important practical applications. They are also inspiring scienti fic research in the field of discrete applied mathematics. Among them are controlled...
