Abstract:
The aim of this work is study a dynamic contact problem between a
deformable body and a foundation where the deformations are supposed
to be small. The contact is with adhesion and normal compliance. The
behavior of this body is modeled by a nonlinear
elastic-visco-plastic law. The evolution of bonding field is
described by a nonlinear differential equation. We derive a
variational formulation of the contact problem and we prove the
existence and uniqueness of its solution. The proof is based on the
construction of three intermediate problems and then we construct a
contraction mapping whose unique fixed point will be the weak
solution of the mechanical problem.
