Proceedings of the IUTAM Symposium held in Bochum, Germany, 25-29 August 1997

During the last decades modelling of inelastic structural behaviour has achieved great attention. Wherever elastic designhas reached its limita sa consequence of increased loading, the related cons titutive rela tions meanwhile have become part of the engineer s practice. However, new materials with complex behaviour, further increasing loads at higher temperatures, as well as the implementation of stronger security demands have led to theconsequence that the preferentially used phenomenological concepts need to be verified and improved continuously. Caused by the a priori non linear character oft he material rela tions, all equations fort he description of every new phenomenon need to be reconsidered. According to this, since about a decade the idea succeeds that constitutive relations which represent material behaviour more re alistically can not only be deduced phe nomenologicallyfrom the laws of continuum mechanics. Sincet he observed behaviour is caused by processes taking place on the microscale, these processes and mechanisms need to be taken into consideration when determining the constitutive relations. The formulation of proper micro macro relations actu ally is one of the main emphases in thermoplasticity in the international research. The intentiono ft he IUTAM Symposium on Micro and Macrostructural Aspects of Thermoplasticity , held at the Ruhr University of Bochum, Germany, from August 25 to 29, 1997, wast o bring together eminent scientistsworking i n different fields of thermoplasticity with the aim thatt hey may exchange their ideas and activate this interaction.

Klappentext

This volume contains contributions presented at the IUTAM Symposium on Micro- and Macrostructural Aspects of Thermoplasticity. The symposium brought together 87 eminent scientists from 13 countries working in the field of thermoplasticity with the aim of exchanging ideas and stimulating interaction. The majority of the lectures covered the main theme of the symposium, with a few of a more general keynote nature and a memorial lecture devoted to the work of Th. Lehmann. This volume begins by presenting basic questions of material modelling. Problems encountered in polycrystalline materials are also discussed and the transition from the micro- to the macroscale is the subject of several papers. The special handling of shape memory materials, phase transformation, and damage is emphasized. A couple of papers are devoted to experimental results and the various aspects of numerical treatment. It has become clear that previously cited problems, though approached from different viewpoints, may often be handled similarly. Moreover, the processing of special cases sensitized for a more accurate treatment in details. The volume will be of interest to researchers in the field of thermoplasticity.
