摘要
本文针对固体力学中的应力问题，应用边界元法建立基本方程，并求解此方程，得出求解线性弹性物体三维应力的式子，以便工程中使用计算机对结构应力进行数值计算。
This paper uses the baundary element method to set up and solve the basic equations for the stress problems in solid mechanics.The solution has been got for three-dimensional stresses of a body,so that the numerical calculations can be carried out on computer for these problems in enginering.
