Self-Consistent Modelling of Plastic and Viscoplastic Polycrystalline Materials

  • A. Molinari
Part of the International Centre for Mechanical Sciences book series (CISM, volume 376)


This lecture describes some self-consistent approaches that are used to model the plastic deformation of strain-rate dependent and of rate-independent polycrystalline materials. A discussion is presented of the grain-matrix interaction law, which in most of the approaches appears to be too stiff. Large strain deformations are considered, and the evolution of the crystallographic texture and of the morphology of grains is accounted for to model the development of the overall anisotropy of the polycrystal.
