Abstract

Abstract

An analysis of the postbuckliag strength of stringer stiffened cylindrical shells,subject to axial compression is described, The method used is this paper is based on plastic analysis extending Murray's method which was used to analyse postbuckliag behaviour of stiffened plates loaded axially and in beading. The mechanism tripping of stringer and crumpling of shell plates is described based on how the test specimens are deformed after buckling.Finally the theoretical analyses are compared with the experimental results of steel specimens. The theoretical results coincide quite well with the ezperimeatal data. It should therefore be possible to use the method described here to analyse postbuckliag strength of stringer stiffened cylindrical shells and to estimate energy absorbtion capsbilities is relation to collison studies.
