固体弹塑性问题边界积分方程的离散

Scatters of Boundary Integral Equation in Elastoplastic Solid

本文建立了适用于一般松软固体，如黄土材料的边界积分方程，并用八节点二次表面等参元和二十节点立方体等参元对所建立的固体弹塑性问题边界积分方程作了离散化研究，可供应力计算使用。

This paper has established a bounary integral equation that sulted general porous solid,e. g. loess material,used element of eight points and twenty points scattersing it,in order to the calculatbo of stress.
