Stress concentration of a strip with a single edge notch

Abstract

This paper deals with the stress concentration analysis of a semicircular and a 60° V-shaped single edge notch in an infinite strip under three different types of loading conditions: (a) uniform tension, (b) in-plane bending and (c) pure tension. The stress field induced by a point force in the semi-infinite plate, Green's function in a closed form, is used to solve those problems. The results show that Neuber's formula gives an underestimated stress concentration factor when the notch is sharp and shallow. The stress concentration factors of 60° V-shaped notches are represented by diagrams for wide use.
