Abstract
This paper describes the construction and external pressure-testing of cylindrical shells fabricated by filling the annulus between two thin steel concentric membranes with an epoxy resin-glass syntatic foam. The investigation was specifically aimed to study the strength-instability interaction of relatively thin composite shells. The experimental behaviour of eight shells is reported and their failure pressures are compared with previously published predictions. The results provided empirical evidence to support a modified Rankine-type interaction curve yielding safe lower bound solutions.
