Based on the superposition method and the conventional Mode III stress field for a sharp Vnotch, the approximate solution for stress field of V-notch with end-hole under out-of-plane shear loading is proposed. This work also shows results of the evaluation on the accuracy of the Mode I and II stress fields for V-notch with end-hole proposed in the previous study by the authors. The stress fields are written in terms of the notch stress intensity factors (NSIFs), and the NSIFs are determined by means of numerical analyses. The effectiveness and validation of the proposed superposition approach are discussed by comparing the results from the present approach with those taken from the literature.
