提出了一种确定各向异性板中V型缺口附近奇异应力场的方法。该方法是基于吴等人最近提出的一种新的边界元公式。[J.Appl.Mech.59,344-348(1992)]与路径无关的积分相结合，将近场与远场联系起来。给出了含有单边裂纹、两个共线边裂纹、一个内部裂纹、一个单缺口和两个对称缺口的板在均匀应力作用下的数值算例。
A method to determine singular stress fields near a V-notch in an anisotropic plate is presented. The method is based on a new boundary element formulation recently proposed by Wu et al. [J. Appl. Mech.59, 344–348 (1992)] coupled with path-independent integrals relating the neartip field to the far field. Numerical examples are given for plates containing a single edge crack, two collinear edge cracks, an internal crack, a single notch, and two symmetric notches under uniform stress.
