Imperfection sensitivity of axially compressed stringer reinforced cylindrical panels under internal pressure

Abstract

This paper is a study of the effects of longitudinal edge stiffness and internal pressure on the buckling and initial postbuckling behavior of axially compressed long cylindrical panels. Two methods of solution are presented. The first is a series solution where the torsional rigidity of the edge stiffeners is not included and the second is a numerical solution where the torsional rigidity of the edge stringers is included. The results show that both internal pressure and the edge stiffener torsional rigidity tend to increase the panel buckling strength and the panel insensitivity to initial imperfections. © 1971, American Institute of Aeronautics and Astronautics, Inc., All rights reserved.
