摘要

A postbuckling analysis is presented for a stiffened, laminated, thin cylindrical shell of finite length subjected to combined loading of external liquid pressure and axial compression. The formulations are based on a boundary layer theory of shell buckling, which includes the effects of nonlinear prebuckling deformations, nonlin- ear large deflections in the postbuckling range and initial geometri- cal imperfections of the shell. The ‘smeared stiffener' approach is adopted for the stiffeners. The analysis uses a singular perturbation technique to determine the interactive buckling loads and post' buckling equilibrium paths. Numerical examples cover the per formances of perfect and imperfect, stiffened and unstiffened cross-ply laminated cylindrical shells. Typical results are presented in dimensionless graphical form.
