β¦ Synopsis
The stress intensity factors of two cracks emanating from a hole in a finite plate is analysed by the Muskhelishviii formulation and boundary collocation method. For Mode I case, the present results compared very favorably with the existing solutions. For the mixed mode problems of inclined cracks, the K, and K,, values have been obtained for varying crack-length to plate-width ratios, a/b, and different crack angles. It has been demonstrated that the convergence of this method is satisfactory. The proposed stress functions and the calculation procedure may be extended to more complex geometrical and loading cases.
