| Abstract: | 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. |
