Abstract

- In this paper, the contact between bodies with elastoplastic behaviour is studied. In order to solve the contact problem, a direct constraint technique is em- ployed. Friction between the bodies is taken into account, and the materials may have different elastoplastic properties. An initial strain BEM formulation is used to study the elastoplastic problem. The material is assumed to obey the Von Mises yield criterion with its associated flow rule. Two numerical examples are presented, to demonstrate the efficiency of the proposed method. Introduction In engineering structures, the transfer of loads is usually achieved through contact. Where contact exists at small r
