摘要
对于弹性力学问题，采用实际边值和虚拟力引起的边界量构造边界误差平方和函数，建立了一套基于最小二乘的改进间接边界积分方程。
For the elasticity problems, a least square error function is constructed by boundary values due to imaginary body forces and the boundary conditions. An improved indirect boundary integral equation is set up. The method can imitate complex boundaries. It is accurate and efficient for the problems with singular bounndaries, especially for stress concentration problems.
