We study a quasistatic frictionless contact problem with normal compliance and damage for elastic-viscoplastic bodies. The mechanical damage of the material, caused by excessive stress or strain, is described by a damage function whose evolution is modelled by an inclusion of parabolic type. We prov

A quasistatic frictionless contact problem is studied, modelled with the Signorini contact condition with a gap function. The material behavior is modelled with an electro-elastic-visco-plastic constitutive law, allowing piezoelectric effects. A weak formulation for the model is given in the form of
## a b s t r a c t In this work, the numerical approximation of a viscoelastic contact problem is studied. The classical Kelvin-Voigt constitutive law is employed, and contact is assumed with a deformable obstacle and modelled using the normal compliance condition. The variational formulation lead
