A study is presented of the post-buckling behaviour and imperfection sensitivity of complete
spherical shells subject to uniform external pressure. The study builds on and extends the …

This paper applies a semi-analytical polynomial method (SAPM) to solve the mechanical
governing equations of nonlinear static and dynamic deformations, free and forced …

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 …

This paper presents numerical results focusing on the buckling behaviour of externally
pressurised imperfect spherical shells. The numerical model followed the recommendations …

We study the buckling of hemispherical elastic shells subjected to the combined effect of
pressure loading and a probing force. We perform an experimental investigation using thin …

This paper addresses localization of the deformation due to buckling that occurs
immediately following the onset of bifurcation in the axisymmetric buckling of a perfect …

Elastic spherical shells loaded under uniform pressure are subject to equal and opposite
compressive probing forces at their poles to trigger and explore buckling. When the shells …

The nonlinear axisymmetric post-buckling behaviour of perfect, thin, elastic spherical shells
subject to external pressure and their asymmetric bifurcations are characterized, providing …

We combine discrete differential geometry (DDG)-based models and desktop experiments to
study supercritical pitchfork bifurcation of a pre-compressed elastic plate under lateral end …

Energy perturbation is applied as a measure in the stability analysis of a spherical shell
subjected to uniform external pressure. The energy barrier (buckling energy) is calculated …
