Approximation of thermoelasticity contact problem with nonmonotone friction

The paper presents the formulation and approximation of a static thermoelasticity problem that describes bilateral frictional contact between a deformable body and a rigid foundation. The friction is in the form of a nonmonotone and multivalued law. The coupling effect of the problem is neglected. Therefore,the thermic part of the problem is considered independently on the elasticity problem. For the displacement vector,we formulate one substationary problem for a non-convex,locally Lipschitz continuous fun...
