dc.description.abstract	The work carried out in this thesis is devoted to the mathematical study of some problems of contact mechanics with friction in a dynamic context with boundary conditions. Thermoelasto viscoplastic, thermoviscoelastic, and electroviscoelastic constitutive laws are considered. For each problem, we derive a variational formulation and then establish existence and uniqueness re sults for a weak solution. The proofs are based on arguments of evolutionary variational inequalities, parabolic inequalities, differential equations, and a fixed point theorem.
dc.description.sponsorship	Le travail réalisé dans cette thèse vise à l’étude mathématique de certains problèmes de mé-canique de contact avec frottement dans un contexte dynamique avec des conditions aux limites.On considère des lois de comportement thermoviscoélastiques, et électroviscoélastiques. Pour chaque problème, nous obtenons la formulation variationnelle, puis nous établissons les résultats d’existence et d’unicité de la solution faible. Les preuves sont basées sur les arguments d’inéquations variationnelles d’évolution, d’inéquations paraboliques, d’équa tions différentielles et de théorème du point fixe.
