Abstract

In general, internal cells are required to solve elastoplasticity problems using a conventional boundary element method(BEM). However, in this case, the merit of BEM, which is the easy preparation of data, is lost. The conventional multiple-reciprocity boundary element method (MRBEM) cannot be used to solve the elastoplasticity problems, because the distribution of initial strain or initial stress cannot be determined analytically. In this paper we show that two- dimensional elastoplasticity problems can
