本文采用一种简单有效的迭代算法，用位移间断法(DDM)模拟裂纹的闭合和滑动。Elvin和Leung(Elvin N，Leung C.)所考虑的半平面次表面裂纹在压痕载荷作用下的问题。Engng FRACT Mech 1999；63：631-48)和DeBremaecker and Ferris(DeBremaecker J-CL，Ferris MC.求解闭合裂纹问题的两种算法的比较。Engng FRACT Mech 2000；66：601-05)使用迭代DDM重新检查。考虑了无摩擦接触和摩擦接触的部分闭合裂纹的情况。给出了亚表面裂纹的应力强度因子和界面裂纹机制的基准结果，并与Elvin和Leung的快速迭代算法以及DeBremaecker和Ferris的路径算法的结果进行了比较。
In this paper, a simple and efficient iterative algorithm is adopted to model crack closure and sliding with the displacement discontinuity method (DDM). The problem of a subsurface crack in a half-plane under indentation loading considered by Elvin and Leung (Elvin N, Leung C. A fast iterative boundary element method for solving closed crack problems. Engng Fract Mech 1999;63:631–48) and DeBremaecker and Ferris (DeBremaecker J-Cl, Ferris MC. A comparison of two algorithm for solving closed crack problems. Engng Fract Mech 2000;66:601–05) is reexamined using the iterative DDM. The cases of a partially closed crack with both frictionless and frictional contacts are considered. Benchmark results for the stress intensity factors and the interfacial crack mechanisms for a subsurface crack are presented and compared with the results obtained from the fast iterative algorithm of Elvin and Leung and those from the PATH algorithm of DeBremaecker and Ferris.
