Virot, E, Kreilos, T., Schneider, T.M. and Rubinstein, S.M., “Stability landscape of shell buckling”, Physical Review Letters [28 Nov 2017, 119 (22):224101] Recent studies show that methods based on the stability landscape of thin cylinders obtained by probing axially compressed shells in the radially inward direction can predict the capacity of

Shells are three dimensional curved structures that are very efficient to support external forces. These are called thin shells when the thickness is small compared to other

Thin-walled cylinders under axial compression are prone to buckling at a load lower than classical analysis would predict due to the imperfection sensitivity of such

Another source of discrepancy is the dependence of buckling loads of cylindrical shells on edge values of longitudinal and circumferential displacements or forces. Also, because tangential

The buckling response of axially compressed cylindrical shells is well known for its imperfection sensitivity. Mapping out a stability landscape by localized probing has recently 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

Abstract The prediction of the critical buckling conditions of shell structures is plagued by imperfection sensitivity. Non-destructive testing through point-load probing has The buckling response of axially compressed cylindrical shells is well known for its imperfection sensitivity. Mapping out a stability landscape by localised probing has recently been proposed

A final application of the probing procedure is to use specific features of the stability landscape to derive non-empirical shell buckling knockdown factors. For example, in previous work the

The stability of structures continues to be scientifically fascinating and technically important. Shell buckling emerged as one of the most challenging nonlinear problems in Crumpling Soda Cans: Predicting the Stability Landscape of Shell Buckling Crushing a soda can from top to bottom is easier if it is dented initially on the The axial buckling capacity of a thin cylindrical shell depends on the shape and the size of the imperfections that are present in it. Therefore, the prediction of the shells‘ buckling capacity is

Shell buckling is characterized by the topographical features of the stability landscape, namely, an unstable flat lake surrounded by a basin with a ridge and valley of stability.
