Superposition approach of the stress fields for blunt V-notches under anti-plane shear loading

Abstract

This paper deals with the Mode III problem for a blunt V-notch. By using the superposition method and the conventional stress field for a sharp V-notch, this work suggests a simple formula which is able to address the Mode III stress fields of blunt Vnotches. The notch stress intensity factors (NSIFs) were estimated from numerical analysis with finite element analysis (FEA). And thereafter, several special cases were considered with the results being compared with those of the literature dealing with same topic.
