Buckling refers to the sudden change in shape of a structure under load, which can lead to failure. Understanding how these shells behave under various conditions, including imperfections and ...

A novel approach using the smeared stiffener method has been proposed, which effectively predicts the critical buckling load and optimizes the design of both perfect and imperfect shells.

Find expert answers in this collaborative article One of the simplest ways to prevent buckling in structures is to increase their stiffness, which is the resistance to deformation under load.

"Localised deformation and randomly shaped imperfections are salient features of buckling-type instabilities in thin-walled load-bearing structures," the PNAS study said. "However, it is generally ...

This analysis is about the determination of the Local buckling utilization of a pipeline rogue buckle to ascertain if the rogue buckle meets acceptance criteria for a combined loading criteria ...

where the postbuckling behaviour changes from thin film to mixed mode to global buckling. The model is validated with the commercial finite-element code Abaqus and criteria are proposed such that the ...

Abstract: This paper uncovers new manifestations of the homoclinic snaking mechanism in the post-buckling regime of a pressurized thin cylindrical shell under axial load. These new forms tend to ...
