摘要：
Boundary value problem of a plate with crack and defect such as the circular and/or elliptical holes is a multi-connected domain problem, this kind of problem is suitable for solving by boundary element method with its higher precision. The sub-region method is used in the paper, a center cracked plate subjected to remote tensile and shear loading is studied numerically. The effect of the circular hole on Mode-I and Mode-II stress intensity factors is studied assuming the plane strain condition, the results are more precise than that of using FEM. The effect of the elliptical hole on Mode-I stress intensity factors is studied as well and some significant results are obtained. (C) 2006 Elsevier Ltd. All rights reserved.
