A Frictional Contact Problem for Piezoelectric Materials with Internal
State Variablesand Normal Damped Response
Abstract
In this paper, we consider a dynamic frictional contact problem between
two electro-elasto-viscoplastic bodies with internal state variables and
damage. The contact is frictional, modeled with a normal damped
condition involving adhesion effect of contact surfaces. We present a
variational formulation for the model and state an existence and
uniqueness result of the weak solution. The proof is based on arguments
of time dependent variational inequalities, differential equations and
fixed point.
