摘要

Based on the stretch tensor, a finite strain formulation of elasto-viscoplasticity is given. In departure from standard formulations based on the decomposition of the deformation gradient, the stretch tensor itself is decomposed into elastic and inelastic parts. The model of elasto-viscolplasticity is the class l one with elastic range and over-stress tensor. A finite element formulation is given based on the enhanced strain concept where the stretch tensor itself is enhanced.
