Stress Analysis of a Blunted Notch in a Clamped Edge

Abstract

A formula for the stress concentration of a rounded notch cut in a clamped edge is derived. In this investigation a notched semi‐infinite plate is subjected to two situations: Uniform tension and uniform shear. The notch has a rounded corner at the end. It is shown that the maximum stress at the tip of a rounded corner can be represented by an infinite series expressed in forms of radius of curvature and the order of Williams stress singularity. The approximate expressions which include only the first few terms of an infinite series are compared with the analytical results. A rational mapping function and complex stress functions are used for the analysis of this displacement boundary value problem.
