A polycrystal plasticity model is used to describe the Portevin - Le Chatelier effect in a velocity controlled tension test. An elastoviscoplastic constitutive model is developed. The resulting fully implicit procedure is introduced into both Taylor (material point) and finite element models. Statistical analysis of the stress drops collected through finite element simulation indicate power law distributions for continuous band propagation, consistent with experimental observations. No "artificial" gradient plasticity formulation is required since spatial gradients exist naturally due to grain incompatibilities.
