Existence of solution for a nonlinear model of thermo‐visco‐plasticity

Leszek Bartczak , Sebastian Owczarek

Abstract

We study a thermodynamically consistent model describing phenomena in a visco-plastic metal subjected to temperature changes. We complete the model with the mixed boundary condition on displacement and stress and Neumann-type condition for temperature. The main result is an existence of solutions.
