IUTAM SYMPOSIUM ON MICROMECHANICS OF PLASTICITY AND DAMAGE OF MULTIPHASE MATERIALS SOLID MECHANICS AND ITS APPLICATIONS Volume 46 Series Editor: G.M.L. GLADWELL Solid Mechanics Division, Faculty ofE ngineering University ofW aterloo Waterloo, Ontario, Canada N2L 3Gl Aims and Scope of the Series The fundamental questions arising in mechanics are: Why?, How?, and How much? The aim of this series is to provide lucid accounts written by authoritative research ers giving vision and insight in answering these questions on the subject of mechanics as it relates to solids. The scope of the series covers the entire spectrum of solid mechanics. Thus it includes the foundation of mechanics; variational formulations; computational mechanics; statics, kinematics and dynamics of rigid and elastic bodies; vibrations of solids and structures; dynamical systems and chaos; the theories of elasticity, plasticity and viscoelasticity; composite materials; rods, beams, shells and membranes; structural control and stability; soils, rocks and geomechanics; fracture; tribology; experimental mechanics; biomechanics and machine design. The median level of presentation is the first year graduate student. Some texts are monographs defining the current state of the field; others are accessible to final year undergraduates; but essentially the emphasis is on readability and clarity. For a list ofr elated mechanics titles, see final pages.

PREFACE The IUT AM Symposium on "Micromechanics of Plasticity and Damage of Multiphase Materials" was held in Sevres, Paris, France, 29 August -1 September 1995. The Symposium was attended by 83 persons from 18 countries. In addition 17 young French students attended the meeting. During the 4 day meeting, a total of 55 papers were presented, including 24 papers in the poster sessions. The meeting was divided into 7 oral and 3 poster sessions. The 7 oral sessions were the following: -Plasticity and Viscoplasticity I and II; -Phase transformations; -Damage I and II; -Statistical and geometrical aspects; -Cracks and interfaces. Each poster session was introduced by a Rapporteur, as follows: -Session I (Plasticity and Viscoplasticity): G. Cailletaud; -Session 2 (Damage): D. Franc;:ois; -Session 3 (Phase transformation; statistical and geometrical aspects): D. Jeulin. The main purpose of the Symposium was the discussion of the state of the art in the development of micromechanical models used to predict the macroscopic mechanical behaviour of mUltiphase solid materials. These materials consist of at least two chemically different phases, present either initially or formed during plastic deformation, when a strain-induced phase transformation takes place. One session was devoted to the latter case. Continuously strengthened composite materials, containing long fibers, were out of the scope of the Symposium. On the other hand, the definition of multiphase materials was extended to damaging materials in which the second phase corresponds to the formation of damaged zones (microvoids, microcracks etc.). Two oral sessions and one poster session were devoted to this topic. The statistical and the geometrical aspects in the mechanical behaviour of these multiphase materials were presented during another oral session and another poster session whereas an oral session was devoted to problems related to cracks and interfaces. In this Symposium, materials with a microstructure such that the usual concepts of continuum mechanics could be applied were essentially considered. Moreover, as a rule, one of the constituent phases of multiphase materials which were presented exhibited a nonlinear behaviour. Two oral sessions and one poster session were devoted to the mechanical behaviour of plastic or viscoplastic multiphase materials. This Symposium clearly showed a growing interest in the development of micromechanical approaches to model the macroscopic behaviour of inhomogeneous materials. Several presentations emphasized the importance of local phenomena, of the spatial phase distribution and its modifications, as well as the importance of an adequate treatment of the nonlinear character of the overall response. The limitations of simplistic homogenization techniques in which the mechanical stress and strain fields are assumed uniform in each phase were also largely underlined. A significant number of presentations were devoted to the coupling effect between damage and constitutive equations. The statistical aspects in the modelling of the mechanical behaviour of multiphase materials, especially their damage behaviour, were also largely discussed. The Editors particularly wish to thank the Bureau of IUT AM, the International Scientific Committee and the local organizing committee. This conference could not have been so suscessful without the excellent conference facilities provided by the "Centre International d'Etudes Pedagogiques" in the ancient Royal Sevres Porcelain Fa::tory. Thanks are also due to the authors and referees who have made this publication possible and to the session chairmen who have contributed to the success of the conference. Special thanks are due to M. Bornert, T. Bretheau and 1. Besson for their very efficient help throughout the preparation and organization of the Symposium. Finally, we would like to express our gratitude to the sponsoring organizations who have supported the Symposium financially, namely the International Union of Theoretical and Applied Mechanics (IUTAM) and a number of French institutions and companies: M.E.S.R., D.G.A.
