The elastoplastic and elasto-viscoplastic deformations not only for the monotonic but also the cyclic loading processes at the general deformation rate ranging from the quasistatic to the impact loadings can be described in a unified manner by the subloading-overstress model, while it is noteworthy that the elastoplastic constitutive equation limited to the description of the quasistatic deformation can be disused. It is desirable to extend the subloading-overstress model to describe the temperature-dependence, since the elasto-viscoplastic deformation behavior is influenced by the temperature in general. Then, the formulation of the subloading-overstress model is extended to incorporate the temperature dependence of Young’s modulus, the isotropic hardening, the kinematic hardening and the elastic-core translation and the thermal strain for metals for the range of temperature in the engineering practice in this article.
