On effects of concentrated loads on perforated sensitive shells of revolution

Sensitive shells are a class of constructions with specific and perhaps unintuitive responses to different loading scenarios. There new emerging applications for capsules open cavities, as the designs optimised maximise payload, sensitivity has be taken into account. Concentrated loads induce singularities that propagate along characteristics surfaces. Perforation patterns do not have strong effect on internal layers. Under symmetric concentrated parabolic hyperbolic there exists critical thickness at which local features solution begin dominate, whereas elliptic cases is always dominant global response. In non-uniform curvature part will dictate even if load acting it. The extensive set simulations been computed using high-order finite element solvers including adaptivity.
