| Abstract: | 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. |
