Radial loading of a cylindrical shell through plate brackets

Abstract

The elastic behaviour of a cylindrical shell subjected to radial load applied through two circumferential plate bracket attachments positioned diametrically opposite each other at the mid length of the cylinder has been investigated experimentally. An existing theoretical analysis, based on the assumption of a uniform distribution of load across a bracket, was modified in the light of the experimental observations which indicated that the assumption was not valid for the size of bracket used.

Experimental stress distributions and maximum values of stress in the cylinder are compared with those calculated from the modified analysis in the text, which showed an improvement on the existing analysis for the proportions of the shell and bracket considered.
