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


A methodology is outlined for incorporating a representation of the behavior of metals based on polycrystal plasticity into a finite element formulation for their deformations. The review begins with a summary of the finite element formulation for equations governing the viscoplastic flow of metals. The anisotropic material response is specified by the averaged response of representative aggregates of crystals residing within the elements. The aggregate behavior is based on models for crystallographic slip in single crystals and hypotheses for computing the average response of crystals comprising the aggregate. Approaches are presented for representing orientations of individual crystals, for describing distributions of crystal orientations, and for updating the distributions with deformation. The methodology is applied to the rolling of face-centered cubic and hexagonal close-packed metals.
