MULTISCALE MODELING OF POLYCRYSTAL PLASTICITY - A WORKSHOP REPORT

The workshop on multi-scale modeling of polycrystal plasticity was hel d on April 9-11, 1997 at the Institute for Mechanics and Materials at the University of California, San Diego in La Jolla, CA. This workshop addressed length-scale issues associated with developing a predictive capability in the modeling of the plastic deformation of polycrystals by the incorporation of more physically based information in the mode ls. The goals of the workshop were to: (1) establish a model system th at is well suited to the multi-scale modeling methodology; (2) explore a set of discrete simulation methods at the continuum-scale, meso-sca le, micro-scale, and atomic-scale; and (3) identify critical links con necting the length scales which will allow information to be passed am ong scales and allow the end goal of predictive models at the continuu m scale. This paper presents the technical summary of the topics cover ed by the speakers at the workshop and a discussion of critical issues at each length scale. Published by Elsevier Science S.A.
