Abstract
In this paper, a nonlocal theory based upon crystalline plasticity is used in Case Of a dislocation cell structure induced during plastic st raining and represented by a two-phase material. By describing convect ive dislocation motion (which appears to be a basic feature of hardeni ng) and storage mechanisms, under some simplifying assumptions, numeri cal simulations exhibit significant effects on the intragranular heter ogeneization, as well as on global results like the Bauschinger effect .
