A new singular element for evaluating stress intensity factors of V-shaped notches under mixed-mode load

In this paper, a new singular element is presented to evaluate stress intensity factors of V-shaped notches subjected to mixed-mode load. The proposed element takes into account special variation of displacements in the vicinity of the notch tip. The singularity at notch tip is variable unlike the crack problem where the displacements around the crack tip have variation of square root of r. In the proposed method, special basis functions...
