Summary

Buckling equations for stiffened cylinders under the specified loading are formulated and solved by means of double Fourier series using the Galerkin process to reduce the solution to the standard algebraic eigen-value problem. Matrices of order 80 by 80 are required for convergence reflecting the complexity of the mode shape describing the buckling patterns.

Simple design curves are developed for determining buckling loads of monocoque cantilever loaded cylinders.

Excellent agreement with test values is demonstrated, indicating that the cylinders are not highly sensitive to imperfections, as is the case of the uniform, axially loaded cylinder. This also follows from the fact that considerable post buckling strength exists for the cantilever loading condition.
