Elastic perfectly plastic structures with temperature dependent elastic coefficients

We study the evolution of elastic perfectly plastic structures where the elastic coefficients depend on temperature, as they are subjected to classical loading and given variation of the temperature field. We prove varitional theorems for the instantaneous fields of velocities and stress rates, and establish the generalized differential equation for the evolution of the stress field.
