Quasiconvex envelope for a model of finite elastoplasticity with one active slip system and linear hardening

Conti, Sergio ; Dolzmann, Georg



Abstract

An explicit characterization of the quasiconvex envelope of the condensed energy in a model for finite elastoplasticity is presented, both in two and in three spatial dimensions. A variational formulation of plasticity, which is appropriate for the first time step in a time discrete formulation of the evolution problem, is used, and it is assumed that only one slip system is active. The model ...
