Collapsible impact energy absorbers: an overview
TL;DR: In this article, the common shapes of collapsible energy absorbers and different modes of deformation of the most common ones are reviewed, such as axial crushing, lateral indentation, lateral flattening, inversion and splitting, while noncollapsible systems such as lead extrusions or tube expansions are considered to be beyond the scope of this review.

The quasi-static crumpling of thin-walled circular cylinders and frusta under axial compression
A.G Mamalis,W Johnson +1 more
TL;DR: In this paper, thin-walled circular cylinders and truncated circular cones of aluminium alloy were subjected to axial static loading and their initial axial length and the outside diameter of cylinders and frusta were kept constant whilst their wall thickness was varied.
Journal ArticleDOI
Extensible plastic collapse of thin-wall frusta as energy absorbers
TL;DR: In this paper, the crumpling of thin-walled frusta, under axial compression, in the ‘concertina’ mode is studied, where the energy expended in bending at the plastic hinges and in stretching the metal between the hinges is minimized for the total decrease in height due to collapse.
Journal ArticleDOI
Mode of collapse and energy absorption characteristics of constrained frusta under axial impact loading
TL;DR: In this article, the energy absorption performance of right circular frusta subjected to dynamic axial load is studied and compared with the results of quasi-static tests and the effect of heat treatment on the collapse behavior and energy absorption is also investigated.
Journal ArticleDOI
The modelling of the progressive extensible plastic collapse of thin-wall shells
TL;DR: In this paper, a theoretical model describing the progressive extensible plastic collapse of thin-wall conical and cylindrical shells is presented, which enables the load-deflection curves during axial compression following the deformation history of the shell to be evaluated.
