Abstract: | An experimental and theoretical investigation of the high explosive containment ability of circular cylindrical shells is presented. Approximate expressions for final circumferential strain or radial displacement as a function of cylinder length are developed in terms of elementary functions, based upon an assumed rigid-plastic material relation for the containment vessel. The material relation includes strain hardening and approximate strain-rate sensitivity. The expressions are presented in a form convenient for containment design purposes and are shown to be in reasonable agreement with experimental results for several container materials and radius-to-thickness ratios. |
