| Summary: | We consider two quasistatic frictionless contact problems for
piezoelectric bodies. For the first problem the contact is
modelled with Signorini's conditions and for the second one is
modelled with normal compliance. In both problems the material's
behavior is electroelastic and the adhesion of the contact
surfaces is taken into account and is modelled with a surface
variable, the bonding field. We provide variational formulations
for the problems and prove the existence of a unique weak solution
to each model. The proofs are based on arguments of time-dependent
variational inequalities, differential equations, and fixed point.
Moreover, we prove that the solution of the Signorini contact
problem can be obtained as the limit of the solution of the
contact problem with normal compliance as the stiffness
coefficient of the foundation converges to infinity. |
