摘要
基于初应力法弹塑性理论,给出了求解三维弹塑性问题边界单元法的一种有效的格式,它适用于较复杂的本构关系,在迭代格式和处理内点奇异积分方面所采用的方法是有效的,能保证精度并加快求解速度。
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.
