The maximum strength of initially imperfect, axially compressed, circular cylindrical shells has been studied with the use of Reissners variational principle, von Karman-Donnell shell theory, and a deformation theory of plasticity. The results of the present analysis reflect families of load-end shortening curves for long circular cylinders. For a given material, each curve relates not only to an imperfection parameter which provides a loading path into the inelastic range but also to the radius-to-wall thickness ratio. Significant maximum strength reductions are obtained, relative to predictions based on linear-elastic theory, for specific materials in the range of radius-to-thickness ratios of practical interest.
