A Kind of Nonlinear Analysis in Solid Mechanics Using Boundary Element Method

摘要

After a brief introduction of the boundary element method for nonlinear analysis of solid mechanics, a kind of boundary element method for the elastoplastic analysis of bimaterial is presented in this paper. In order to raise the efficiency of the bimaterial fundamental solutions, Dundurs and Hetenyi solutions are applied as the kernels of boundary integral equations. A numerical example of elastoplastic analysis of a bimaterial square plate with a circular hole under uniform tension is presented to illustrate the applicability of the presented method to nonlinear analysis in solid mechanics.
