Global existence of solutions to the nonlinear thermoviscoelasticity system with small data

Jerzy A. Gawinecki, Wojciech M. Zajączkowski


We consider the nonlinear system of partial differential equations describing
the thermoviscoelastic medium ocupied a bounded domain $\Omega\subset\mathbb{R}^3$.
We proved the global existence (in time) of solution for the nonlinear
thermoviscoelasticity system for the initial-boundary value problem with the
Dirichlet boundary conditions for the displacement vector and the heat flux at
the boundary. In the proof we assume some growth conditions on nonlinearity
and some smallness conditions on data in some norms.
