| Abstract: | The estimation method based on hybrid stress element combined with line-spring model is used tocalculate the stress-intensity factors of surface cracked plates. The numerical results show that thestress-intensity factors given by this method are in good agreement with those by 3-D finite element method, more accurate than those by the method based on displacement finite element combined with line-spring model. |
