Buckling and postbuckling behaviour of perfect and imperfect cylindrical shells of finite length subject to combined loading of external pressure and axial compression are considered. Based on the boundary layer theory which includes the edge effect in the buckling of shells, a theoretical analysis for the buckling and postbuckling of circular cylindrical shells under combined loading is presented using a singular perturbation technique. Some interaction curves for perfect and imperfect cylindrical shells are given. The analytical results obtained are compared with some experimental data in detail, and it is shown that both agree well. The effects of initial imperfection on the interactive buckling load and postbuckling behaviour of cylindrical shells have also been discussed.read more

Mechanical stability of functionally graded stiffened cylindrical shells

A simplified method of elastic-stability analysis for thin cylindrical shells I : Donnell's equation
TL;DR: In this article, the authors presented a unified viewpoint for the buckling of cylinders with simply supported edges on the basis of a unified view. But the results in each case may be expressed in terms of two non-dimensional parameters, one dependent on the critical stress and the other essentially determined by the geometry of the cylinder.
A simplified method of elastic-stability analysis for thin cylindrical shells
TL;DR: In this paper, a modified form of the Donnell's equation for the equilibrium of thin cylindrical shells is derived which is equivalent to the original equilibrium but has certain advantages in physical interpretation and in ease of solution.
