Failure Analysis of Initially Imperfect, Axially Compressed, Orthotropic, Sandwich and Eccentrically Stiffened, Circular Cylindrical Shells

Abstract

The maximum strength analysis of initially imperfect, axially compressed, orthotropic, sandwich and eccentrically stiffened, circular cylindrical shells has been developed through the use of Reissner's variational principle, von Karman-Donnell kinematics, and a deformation theory of plasticity. For a given material and for the special cases of isotropic sandwich cylinders and conventional cylinders with eccentrically located longitudinal stiffeners, the results of the analysis reflect significant reductions in load- carrying capability in the range of 'effective' radius-to-thickness ratios of practical interest.
