QuasistaticThermoviscoelastic Frictional Contact Problem with Damped Response

摘要

We analyze a problem which describes the frictional contact between a thermoviscoelastic body and a rigid foundation, The process is assumed to be quasistatic and the contact is modeled by a general normal damped response condition with friction law and heat exchange, Then we present a variational formulation of the problem, which is set in an abstract form as a system of evolution equations for the displacements and temperature, We establish the existence and uniqueness of the weak solution, using general results on evolution equations with monotone operators and fixed point arguments. Finally, we study the continuous dependence of the solution with respect to the initial data and contact conditions.
