报告人简介

Franz Roters是德国马克斯·普朗克铁研究所(Max-Planck Institut für Eisenforschung GmbH,MPIE)微观结构物理与合金设计部、理论与模拟组组长,德国材料学会DGM计算机模拟技术委员会主席,开源晶体塑性有限元软件DAMASK开发者,著有《Crystal Plasticity Finite Element Methods In Materials Science And Engineering》。DAMASK软件旨在研究材料在多尺度下的力学响应,可以模拟单晶尺度到结构件尺度范围内多物理现象(如晶体塑性、热、损伤等),实现多尺度、多场耦合的晶体塑性分析。

报告摘要

DAMASK – The Düsseldorf Advanced Material Simulation Kit for modeling multi-physics crystal plasticity, thermal, and damage phenomena from the single crystal up to the component scale Crystal Plasticity (CP) modeling is a powerful and well established computational materials science tool to investigate mechanical structure–property relations in crystalline materials. It has been successfully applied to study diverse micromechanical phenomena ranging from strain hardening in single crystals to texture evolution in polycrystalline aggregates.

This online lecture will focus on the fundamentals of crystal plasticity as well as DAMASK including the constitutive laws, kinematics, homogenization schemes, and multiscale approaches. we also present some examples including in particular comparisons of the predictions with experiments. The applications stem from such diverse fields as orientation stability, microbeam bending, single-and bicrystal deformation, nanoindentation, recrystallization, multiphase steel (TRIP) deformation, and damage prediction for the microscopic and mesoscopic scales and multiscale predictions of rolling textures, cup drawing and stamping simulations for the macroscopic scale.
