The Maximum Strength of Initially Imperfect, Axially Compressed, Circular Cylindrical Shells
Abstract
The maximum strength of initially imperfect, axially compressed, circular cylindrical shells has been studied with the use of Reissner's 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.
