| Abstract: | In this paper, the deformation of thermal elastic-viscoplasticity has been studied by means of the dislocation theory and thermal elastoplastic theory. According to the macroproperties and microproperties of material, we have studied the constitutive relationship of inelastic strain rate. Thus, the incremental stress-strain epuation is derived. |
