Stress Concentrations Around Cut-outs in a Cylinder

Abstract

A considerable amount of theoretical investigation has been undertaken recently, into the stress concentrations arising in the vicinity of cut-outs in aircraft pressure cabins. Papers which analyse the stress concentrations around circular, elliptical, and square reinforced cut-outs, under various loading conditions have been presented by Mansfield, Hicks and Wittrick. In all of these investigations, the problem of the cut-out in a cylinder has been reduced to a problem of an infinite plane sheet containing a hole, and the effects of the curvature have been generally assumed to be insignificant.
