Tension and In-Plane Bending of a Strip with A 60°V-Shaped Single Edge Notch

摘要

This paper deals with the stress concentration analysis of a semi-circular or a 60° V-shaped single edge notch in an infinite strip under remote tension and in-plane bending. The stress field induced by a point force in a semi-infinite plate is used to solve these problems. The results show that the Neuber formula gives an underestimated stress concentration factor when the notch is sharp and shallow. In addition, the stress concentration factors of 60° V-shaped notches are also represented by diagrams.
