摘要
建立了无限平板内埋椭圆形裂纹的线弹簧模型，用积分变换方法推导了问题的控制积分方程和应力强度因子的表达式，给出了数值结果，并与现有交替迭代解进行了比较。
A Line spring model for a embedded elliptic crack in an infinite plate is established in this paper. The governing equations and the formula of stress intensity factor are formulated with integral transfer method. The numerical results are presented and compared with those of the alternating method, and have shown that the application of the model is reasonable.
