Abstract:
We consider a mathematical model which describes the antiplane
shear deformation of a cylinder in frictional contact with a rigid
foundation. The contact is bilateral and is modelled with a total
slip rate dependent friction law. The material is assumed to be
electro-viscoelastic and the foundation is assumed to be
electrically conductive. First, we describe the classical
formulation for the antiplane problem and we give the
corresponding variational formulation which is given by a system
coupling an evolutionary variational equality for the displacement
field and a time-dependent variational equation for the electric
potential field. Then we prove the existence of a unique weak
solution to the model. The proof is based on arguments of
variational inequalities and by using the Banach fixed-point
Theorem.
