SUBDOMAIN METHODS IN STRUCTURAL MECHANICS

The principle of subdomain methods has been introduced many years ago1 and such methods have been used with success in recent years. In this paper, we discuss some methods used to solve the condensed system res ulting from the Schur complement method. We will present the hybrid me thod and a mechanical application: the contact problem between two def ormable solids. In the case of such a problem, we propose two methods: one for the contact with friction and one for the contact without fri ction. Finally, the results of validation tests for both proposed appr oaches are given.
