The authors consider antiplane shearing motions of an incompressible viscoplastic solid. The particular constitutive equation employed assumes that the stress tensor has an elastic component and a component which can exhibit hysteresis. The model exhibits both kinematic and isotropic hardening. The results consist of a set of energy type estimates for the resulting system, L{sub 2} contractivity estimates for the solution operator, and finally an analysis of the approach of the system to a rate independent model as a distinguished parameter describing the flow rule approaches zero. The authors also include some computational results for simple piecewise constant data.
