Etude mathématique de quelques problèmes aux limites en élasto-viscoplasticité

Abstract

Topic will focus on the mathematical analysis of problems modeling the frictional contact without friction or an elasto-viscoplastic body, subject to the risk of damage with a rigid base or deformable. In the first problem, the contact is modeled with normal damped reponse, the process is dynamic. In the second problem, the contact is modeled with normal compliance, the process is quasistatic.
