Multi-scale Analysis of Polycristalline Metals and Composites

摘要

Multi-scale methods for the inelastic modelling of materials were already developed since a long time. We will concentrate here on the highest scales,for metals and alloys and for some composites, considering scale changes from the crystal plasticity level in polycrystals to the level of the structural component analysis. Lower scales, involving methods like discrete dislocation dynamics, molecular dynamics or atomistic simulations are out of the scope of the present discussion. We also limit the considered area to the context of elasto-plasticity and viscoplasticity, at moderate strains.
