An anisotropic large deformation thermoviscoplastic constitutive model has been formulated in which flow is regarded as a dissipative process characterized by a ''driving energy'', a threshold energy, and a retardation time. Thermodynamic state functions such as internal energy are derived explicitly as functions of the state variables, namely temperature, elastic strain and flow strain. The model developed here is relevant to applications such as temperature rise and stress relaxation in metals under shock loading.
