A bionic tree-liked fractal structure as energy absorber under axial loading
TL;DR: In this article, a tree-liked fractal method is proposed to develop a novel protective structure with great energy absorption, and the theoretical model of the tree-like fractal structure is introduced to analyze their energy absorption under quasi-static and dynamic loads.
Deployable System for Crash-Load Attenuation
Sotiris Kellas,Karen E. Jackson +1 more
TL;DR: In this paper, an externally deployable honeycomb structure is investigated with respect to crash energy management for light aircraft, where flexible hinges between cell wall junctions enable effortless deployment, and a variety of deployment options such as linear, radial, and/or hybrid deployment methods are discussed.

Dynamic and Static Axial Crushing of Axially Stiffened Square Tubes
Norman Jones,R. S. Birch +1 more
TL;DR: In this paper, the axial impact of thin-walled tubes with square cross-sections, which incorporate axial stiffeners, was studied, and the experimental results on mild steel specimens of side width c suggest, for a given impact energy, that the permanent axial displacements are not reduced significantly by the addition of stiffeners unless T/c exceeds a certain value.

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.
