The derivation of an a posteriori error estimator for frictionless contact problems under the hypotheses of linear elastic behaviour and inΓΏnitesimal deformation is presented. The approximated solution of this problem is obtained by using the ΓΏnite element method. A penalization or augmented-Lagrang
In this paper a further method is presented to solve problems involving contact mechanics. The basic idea is related to a special modification of the unconstrained functional to include inequality constraints. The modification is constructed in such a way that minimal point of the unconstrained pote
