提出了一种二维裂纹问题的数值解法，该方法考虑了裂纹扭结和裂纹面间摩擦接触的影响。该方法基于沿裂纹的合力的积分方程。考虑了接触裂纹表面之间的库仑摩擦。通过考虑半平面上的表面和次表面分段直线裂纹，证明了数值实现的可行性。数值结果表明了该方法的有效性和可靠性。
A numerical method is presented for the solution of two dimensional crack problems including the effects of crack kinks and frictional contact between crack faces. The method is based on an integral equation for the resultant forces along a crack. Coulomb friction between contacting crack surfaces is taken into account. The numerical implementation is demonstrated by considerations of surface and sub-surface piece-wise straight line cracks in a half-plane. Numerical results are presented to illustrate the efficiency and the reliability of the presented method.
