Abstract

A new boundary element scheme for the elastic contact analysis N. Kamiya,* T. Nishiki* School of Informatics and Sciences, Nagoya University, Nagoya 464-01, Japan ABSTRACT A new analysis scheme for the two-dimensional elastostatic contact problems is proposed in this paper. Principal objective is to promote high computational efficiency for the above-mentioned problem, specifically for the unknowns boundary identification corresponding to a variety of contact phases including separation. Two elastic bodies are treated individually by the new formulation similar to the flexibility method, and are coupled to satisfy the conditions specified on the contact region, which is oriented to make fit for parallel computation. The scheme can reduce recomputation of system matrices for each iteration stage and their modification is sufficient of only small part for the assumed contact region. Some numerical examples are shown for the cases with and without friction. INTRODUCTION
