Buckling of Axially Compressed Imperfect Orthotropic Shells with Elastic Edge Supports

摘要

A rigorous solution is presented for the case of axially compressed stiffened cylindrical shells with general imperfections, where the edge supports are provided by symmetrical or unsymmetrical elastic rings. The circumferential dependence is eliminated by a truncated Fourier series. The resulting nonlinear 2-point boundary value problem is solved numerically via the 'Shooting Method.' The changing deformation patterns resulting from the different degrees of interaction between the given initial imperfections and the specified end rings are displayed. Recommendations are made as to the minimum stiffnesses required for optimal load carrying configurations.
