Dynamic progressive buckling of circular and square tubes
W. Abramowicz,Norman Jones +1 more
TL;DR: In this paper, a series of over 120 axial crushing tests were conducted on circular and square steel tubes loaded either statically or dynamically, and approximate theoretical predictions for static and dynamic progressive buckling were developed.

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.

Dynamic axial crushing of circular tubes
W. Abramowicz,Norman Jones +1 more
TL;DR: A series of axial crushing tests on steel circular cylindrical shells loaded either statically or dynamically is reported and compared with various theoretical predictions and empirical relations in this article, where a modified version of Alexander's theoretical analysis for axisymmetric, or concertina, deformations gives good agreement with the experimental results when the effective crushing distance is considered and provided that the influence of material strain rate sensitivity is retained in the dynamic crushing case.

On the crashworthiness performance of thin-walled energy absorbers: Recent advances and future developments
TL;DR: In this article, a comprehensive overview of the recent developments in the area of crashworthiness performance of thin-walled (TW) tubular components is given with a special focus on the topics that emerged in the last ten years such as crashworthiness optimisation design and energy absorbing responses of unconventional TW components including multi-cells tubes, functionally graded thickness tubes and functionally graded foam filled tubes.

Static and dynamic axial crushing of square thin-walled aluminium extrusions
TL;DR: In this article, an experimental investigation was carried out to study the behavior of square thin-walled aluminium extrusions in alloy AA6060 subjected to axial loading, and both static and dynamic tests were performed and the primary variables were the wall thickness and temper of the square tubes and the impact velocity of the projectile.

The effective crushing distance in axially compressed thin-walled metal columns
TL;DR: In this paper, a simplified theoretical model of a compressed rigid-linearly strain hardening metal strip is studied and a closed-form solution is derived for the crushing distance of unstiffened as well as transversly stiffened box columns.
