Abstract
In this paper, we are interested in a contact problem between a thin s hell and a rigid punch. We propose a numerical method for solving this problem. This method is based on an incremental process and the use o f the conjugate gradient method. The context of this work is the isotr opic elastoplastic material with large strains in the quasi-static sta te with the Lagrangian formulation updated for each loading increment. Some numerical results are given to validate the proposed numerical m ethod. (C) 1998 Elsevier Science Ltd. All rights reserved.
