The Landau-Ginzburg func- tional and Rayleigh dissipation function are used to describe the thermoelastic and viscoelas- tic response of the body. A nonclassical heat conduction equation is derived to describe the propagation of the heat inside the body. The plasticity is introduced by the rate-dependent fully implicit backward Euler return mapping scheme with a phenomenological isotropic hardening. Within this model, the complex microstructural changes are consequences of the given Landau free energy functional, nite strain rates, heat conduction, and plasticity.
