Abstract

Existence and uniqueness of a weak solution for dynamical frictional contact between an electro-viscoelastic body and a rigid electrically non-conductive obstacle is established. The contact is modelled with a simplified version of Coulomb's law of dry friction in which the coefficient of friction depends on the slip. The proof is based on the regularization method, Faedo-Galerkin method, compactness and lower semicontinuity arguments.
