Abstract The elastic buckling of shell structures such as spherical shells subject to external pressure and cylindrical shells loaded in axial compression is highly sensitive to imperfections and often catastrophic. Recent studies of spherical shells have provided accurate quantitative results for the relation between the buckling pressure and the amplitude and shape of geometric imperfections and, additionally, quantitative results for the energy barrier that must be overcome to buckle the… Expand

Nonlinear dynamics of spherical shells buckling under step pressure
TLDR
Damping plays an important role in dynamic buckling because of the time-dependent nonlinear interaction among modes, particularly the interaction between the spherically symmetric ‘breathing' mode and the buckling mode. Expand

TLDR
The true significance of the Maxwell energy criterion load was showed in predicting the sudden onset of "shock sensitivity" to lateral disturbances, and how these concepts relate to the response and energy barriers of an axially compressed cylindrical shell. Expand
