The Max-Planck-Institut für Eisenforschung in Düsseldorf is organizing the 4th International Symposium on Computational Mechanics of Polycrystals and we would like to invite you and your research colleagues to participate in this event.This symposium is part of a biannual series of symposia that originated with the establishment of the first joint research group formed between the Max Planck Society and the Fraunhofer Society and investigating Computational Mechanics of Polycrystals. Scope Plastic deformation of polycrystals is the result of a complex interplay of deformation mechanisms in individual grains and grain interactions. The mechanims mediating plastic deformation, e.g. dislocation glide, mechanical twinning, or displacive phase transformations, occur on the atomic scale. However, the macroscopic response of polycrystalline materials is heavily influenced by a hierarchy of microstructures, as for example precipitate structure, dislocation arrangement, grain boundaries, or crystallite orientation distribution. To arrive at computationally efficient material models various coarse-graining steps are necessary to incorporate the small-scale behaviour in effective continuum descriptions. Simulation can replace expensive and time-consuming experiments in the design of components as well as of the tools for their production. However, accurate material models of polycrystal mechanics, which take the microstructure evolution into account, are indispensable for the achievement of such potential cost-savings and reduction in development times. The symposium shall provide an up-to-date overview on the multi-scale modelling and simulation of polycrystal plasticity of metals. Special attention shall be given to industrially relevant multi-phase materials and materials showing mechanical twinning and phase transformations as for instance complex-phase steels, TRIP/TWIP steels, and Magnesium. In this spirit, we are looking forward to experimental, theoretical and computational contributions on all involved length scales. Topics include but are not restricted - fundamental mechanisms of crystal plasticity - TWIP/TRIP effect - behavior of grain ensembles - coarse-graining in polycrystal deformation - materials processing … The event will take place on July 14th and 15th, 2014 in the Max-Planck-Institut für Eisenforschung at Max-Planck-Straße 1, 40237 Düsseldorf, Germany. If you would like to attend this event, then please register online before April 30st 2014. We emphasize that registration is mandatory and that there are limited places only. A participation fee of 100 Euros applies.
