A MULTIVALUED BOUNDARY INTEGRAL-EQUATION FOR ADHESIVE CONTACT PROBLEMS

The present paper proposes a boundary integral equation (BIE) formulat ion for adhesive contact interface problems, i.e. problems involving i nterfaces glued by adhesives where unilateral contact conditions also hold, ii non-monotonic, multivalued law is assumed to describe the beh aviour of the adhesive tangential to the interface direction, which le ads to a hemivariational inequality problem. For the numerical treatme nt of the non-convex-non-smooth optimization problem, a new method is proposed which reduces the initial problem to a sequence of simple qua dratic programming problems.
