| 摘 要： | 研究含边裂纹桥墩的Saint-Venant扭转,将问题划归为裂纹上边界积分方程的求解。提出了新的边界元数值方法,对分别含有圆弧边裂纹和直线边裂纹的典型问题进行了数值计算,并与用Gauss-Chebyshev求积法计算的直裂纹情形结果进行了比较,证明了本文公式的正确性和有效性。

| Abstract: | The Saint-Venant torsion problems of a pier with curvilinear edge cracks were considered and reduced to solving the boundary integral equations only on cracks. The new method for boundary element were given. Some typical torsion problems of a cylinder involving a straight and curvilinear edge crack were calculated .The obtained results for the case of straight crack agree with those given by using the Gauss-Chebyshev integration formulas,which demonstrates the validity and applicability of the present boundary element method. |
