Abstract:
The aim of this paper is to study a quasistatic contact problem between a
nonlinear elastic body and a foundation. The contact is adhesive and
frictional and is modelled with a version of normal compliance condition and
the associated Coulomb's law of dry friction. The evolution of the bonding
field is described by a first order differential equation. We establish the
variational formulation of the mechanical problem and prove an existence
result of the weak solution if the coefficient of friction is sufficiently
small by passing to the limit with respect to time. The proofs are based on
arguments of time-discretization, compactness, lower semicontinuity and
Banach fixed point.
