Quasistatic Elastic Contact with Adhesion

الملخص EN

The aim of this paper is the variational study of the contact with adhesion between an elastic material and a rigid foundation in the quasistatic process where the deformations are supposed to be small.

The behavior of this material is modelled by a nonlinear elastic law and the contact is modelled with Signorini's conditions and adhesion.

The evolution of bonding field is described by a nonlinear differential equation.

We derive a variational formulation of the mechanical problem, and we prove the existence and uniqueness of the weak solution using a theorem on variational inequalities, the theorem of Cauchy-Lipschitz, a lemma of Gronwall, as well as the fixed point of Banach.
