Static and kinetic limit loads of spherical shells

perturbation sensitivity and limit loads of shells are widely discussed phenomena. Both phenomena may be classified with respect to the type of a perturbation. As perturbations influence the stability of shells, the identification of unfavourable perturbations is essential. The perturbation energy concept enables one to identify the unfavourable non-initial perturbation loads and to evaluate the perturbation sensitivity of fundamental states by the perturbation energy. Hence, the presented paper discusses the perturbation sensitivity and the limit loads of simply supported spherical shells under the radial pressure by the perturbation energy concept.
