An elastic/viscoplastic theory that includes anisotropic strain hardening is presented. The theory is a combination of the elastic/viscoplastic formulation of Perzyna [4] and the anisotropic hardening model for time-independent plasticity of Mroz [6]. The theory is used in the analysis of pressure-shear plate impact experiments on commercially pure alpha titanium. Good agreement between theory and experiment is observed.
