Analytical model of thin-walled corrugated tubes with sinusoidal patterns under axial impacting
TL;DR: In this article, three hinge mechanisms and a theoretical model of dynamic progressive buckling of corrugated tube under axial impacting are proposed. And the results conclude that displacement and impacting force are related to the eccentricity factor and the amplitude factor.

Effects of the triggering of circular aluminum tubes on crashworthiness
TL;DR: In this article, an explicit finite element method (FEM) is used to model and analyse the behavior of thin-walled circular aluminum tubes to absorb the impact energy during axial crash.

Key performance indicators of tubes and foam-filled tubes used as energy absorbers
TL;DR: In this article, a set of key performance indicators (KPIs) for assessing and comparing the energy absorbing performance of tubular structures with various configurations is proposed, so as to guide the design of energy absorbers whilst to facilitate parameter optimization.
Journal ArticleDOI
A novel tailor-made technique for enhancing the crashworthiness by multi-stage tubular square tubes
TL;DR: In this article, the authors proposed a tailor-made technique for crashworthiness design by performing a combination of two or more energy absorption techniques to fulfill the crashworthy designer requirements, which is adapted to have the ability of implementation by different structural configurations.

Dynamic axial crushing of square tubes
W. Abramowicz,Norman Jones +1 more
TL;DR: In this paper, the axial progressive crushing of square box columns using a kinematically admissible method of analysis was investigated and four deformation modes which govern the behaviour for different ranges of the parameter c/h.

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.

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.

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.
