Abstract:
 We consider a quasistatic frictional contact problem for an electro
 elastic-viscopalastic body with damage and adhestion.
 The contact is modelled with normal compliance. The adhesion of
 the contact surfaces is taken into account and modelled by a surface variable.
 We derive variational formulation for the model which is in the form of a
 system involving the displacement field, the electric potential field,
 the damage field and the adhesion field. We prove the existence of a
 unique weak solution to the problem. The proof is based on arguments
 of time-dependent variational inequalities, parabolic inequalities,
 differential equations and fixed point.
