Basic ingredients,development of phenomenological models and practical use of crystal plasticity

摘要

This part is an introduction to phenomenological crystal plasticity models, to their properties and their use either in component calculations or in microstructure modelling. Time dependent or time independent versions of the models are presented. The applications deal with single crystal or polycrystalline materials. In this last case, the aggregate is modelled either by a finite element mesh, in order to represent the local microstructure, or by using so called uniform fields models, which allow to introduce the average effect of each crystalline phase in the global behaviour.
