| 摘 要： | 证明了柱体自由扭转的边界积分方程被积函数的散度等于零，将翘曲函数表示为翘曲势函数在边界点的数值计算，避免求解奇异的数值积分。实例计算表明，该表度较高。

| Abstract: | Testifying the divergence free property of the pillar free torsion boundary element method integrand, warping functions can be converted into the numerical evaluation of torsion potential functions at the boundary points and the singular numerical integrals are not needed at all. Numerical results are present to show the excellent accuracy of the new method. |
