| 摘 要： | 本文通过对半无限正交各向异性平面Fourier变换,建立了一种特殊位移模式的应力场计算公式.解决了一外形轮廓曲线为f(χ)的刚性楔块插入半无限长裂纹问题,建立了求解分离坐标和应力强度因子的方程式.其特例均与各向同性体相应问题的解一致.

| Abstract: | By Fourier transform method to the orthotropic half-plane, a set of calculating stress field formulae was established under the case of particular boundary displacement model, and then the problem of a symmetrical rigid wedge whose surface was defined by f(x) inserted into a half infinite crack was solved. The equations for determining separation point and stress intensity factor were put forward in this paper. As a particular case the solutions were fully unified with the isotropic results given in [1]. |
