Abstract
Finite element calculations are performed for crystalline solids subjected to plane strain tensile loading. Using Asaro`s double slip model, shear band developments in single crystals are analyzed. The effect of various rate sensitivities and latent hardening parameters on microscopic plastic behavior was clarified. Moreover the deformation behavior of polycystals which have grain boundaries was compared to that of single crystals.
