Abstract
In this paper we review some approximation and numerical results presented
in [7],[10]. A two-dimensional elastic body obeying nonmonotone contact
laws is considered. The mathematical model of this problem is described
by means of hemivariational inequalities. We shall present a stable and
convergent finite element approximation for it and some numerical results
obtained by nonsmooth optimization methods.
1 Introduction
Hemivariational inequalities, generalizations of variational inequalities, were
introduced by Panagiotopoulos [12]-[14]. They are based on the notations
of the generalized gradient and the generalized directional derivative of a
nonconvex, nonsmooth function (see [1]). By means of them we can math-
ematically describe me
