Abstract

Abstract: oundary element method is used for solving 3-D elasto-plastic contact problems. The boundary integral equations of 3-D elasto-plastic contact problems without friction are derived,and the numerical techniques are discussed.Finally,in comparison with numerical results of finite element method,those of boundary element method show that the presented method is successful.

Key words: boundary element method, contact load, elastoplasticitp, numerical analysis
