Initial Postbuckling Behavior of Stiffened Cylindrical Shells

Abstract

A theory developed by W. T. Koiter for the initial postbuckling behavior of thin-walled shells is applied in an analysis of the imperfection sensitivity of ring-and-stringer stiffened cylinders subjected to axial compression. The cylinders are considered to be simply supported, and both eccentricity and torsional rigidity of stiffeners are taken into account. Values of a so-called imperfection sensitivity parameter are determined for particular stiffened cylinders, and the suitability of the parameter as a practical measure of imperfection sensitivity is examined. Theoretical results are correlated with available data for the experimental buckling loads of stringer stiffened cylinders. The evidence for the suitability of the parameter as a practical measure of imperfection sensitivity is judged to be promising but not conclusive.
