| Abstract: | An efficient BEM scheme is suggested to solve the three-dimensional elasto-plastic probelms, based on the elasto-plastic theory resulting from initial stress approach. It is suitable to complicated constitutional relations and effective to iterative scheme and treament of kernel's singular integral, thus ensuring the accuracy required and speeding up the solving process. |
