Recent advances in contact mechanics: modelling & mathematical analysis.

Abstract:
Recent results in the study of contact problems involving deformable solids will be presented. The contact is modelled with the Signorini condition or with normal compliance. Friction is described with a versionof the Coulomb law. The material behaviour follow elastic-viscoplastic constitutive law in which the piezzoelectric effect is taken into account. Existence and possibly uniqueness results are presented as well as numerical simulation.
