In this paper,the kinked cracks of a semi-infinite plate subjected to extension loading are systematically investigated by using the Body Force Method (BFM).
工程结构中的裂纹扩展时往往呈现拐折，所以折裂纹的研究成为重要课题。
By using the obtained scattered field of the single crack, Cauchy type singular integral equations for the broken crack are established.
利用单裂纹的散射场建立了折线裂纹在SH波作用下的Cauchy型奇异积分方程 。
The point screw dislocation solutions of bimaterial ar e used to establish the Cauchy type integral equations of a broken crack crossin g the bimaterial interface.
利用螺位错基本解建立了和界面相交的折线裂纹的Cauchy型积分方程 。
