Abstract

The paper deals with some new evolution equations for gradient viscoplasticity. Geometric and kinematic aspects of intragranular as well as intergranular plastic deformation of polycrystals are briefly discussed. Low-order inelastic polycrystals with homogeneous grain strains are considered. A homogenization of total, plastic and elastic strains has been done. By tensor representation applied to 3-tensors as well as to 2-tensors a simple case of gradient theory is formulated with a new evolution equation for plastic stretching gradient. An endochronic thermodynamics covering creep-plasticity interaction is applied.
