Intensity of Corner and Stress Concentration Factor

Abstract

The relation between the stress intensity of the corner with an arbitrary angle and the stress concentration factor is investigated. In the thin plate bending problem and the plane elastic problem, the relation is concerned with stress conditions, symmetric to the bisector of a re‐entrant corner angle ranging from 180°–360°. If this relation is known, it is possible, from the expression of stress concentation factor, to determine the stress intensity of the corner with an arbitrary angle. If the stress intensity is known, on the contrary, it is possible to determine the coefficient of the first term in the series for the stress concentration factor. A procedure for numerically determining the stress intensity of the corner is also proposed.
