A computational program for three dimensional stress analysis with boundary element method was developed on the basic of solution of Kelvin problem, and its availability was verified with some examples. The results demonstrate that this program is effective and valuable for solving the problems of three dimensional stress,especially for analyzing the problems of stress centralization. The technique of dynamic allocation memory and automatic selecting integration points were adopted. The block process method was used in the program for solving equation system. The computer resource can be saved effectively and the program can increase the scale of solved problems. This program is useful for resolving the complicated problems in mechanical engineering.
