We measure the response of cylindrical shells to poking and identify a stability landscape, which fully characterizes the stability of perfect shells and imperfect ones in the case where a single defect dominates. We show that the landscape of stability is independent of the loading protocol and the poker geometry. Our results suggest that the complex stability of shells reduces to a low dimensional description. Tracking ridges and valleys of this landscape defines a natural phase-space…

Nonlinear buckling behavior of a complete spherical shell under uniform external pressure and homogenous natural curvature.

It is shown that due to a mechanical analogy between pressure and curvature, positive natural curvatures can severely destabilize a thin shell, while negative natural curvature can strengthen the shell against buckling, providing the possibility to design shells that buckle at or above the theoretical limit for pressure alone, i.e., a strengthening factor.

Buckling of Shells

In many examples in the preceding chapters we have seen that shells can be very thin-walled and that they very often are subjected to compressive stresses in extensive areas. The question arises

These fully nonlinear solutions embedded in the stability boundary of the unbuckled state constitute critical shape deformations and may be a step towards explaining when the buckling and subsequent collapse of an axially loaded cylinder shell is triggered.
