All cylindrical pressure vessels require end closures and these are usually domed or conical in shape. The resistance to buckling under external pressure may be drastically improved by introducing ring-stiffening. This research investigated the buckling performance of cones (for use as end closures) with various sizes of ring-stiffeners using experimental and theoretical approaches. The accuracy and the ease with which to predict the buckling pressures of different ring-stiffened cones were examined. The paper contributes broadly to improving the structural efficiency of submarine structures or any pressure vessel systems subjected to external pressure.
