Dans ce travail, on propose une formulation variationnelle du problème de contact en grandes transformations avec frottement de Coulomb. Il s’agit d’une. This work is a continuation of [1]. We give a space‐time variational formula to the problem of the scattered acoutic wave by a hard body, using the double layer. L’objet de cette th`ese est l’étude d’une méthode variationnelle en mécanique de la rupture, proposée par G.A. Francfort et J.-J. Marigo. Dans cette formulation.
