On crushing characteristics of different configurations of metal-composites hybrid tubes
TL;DR: In this paper, the authors explored the crushing characteristics involving energy absorption and damage behaviors of three different configurations of hybrid aluminum/CFRP under quasi-static axial loading and found that the hybrid tube H-I (i.e., the aluminum tube internally filled with a CFRP tube) offers the best results.

Crushing analysis and multiobjective crashworthiness optimization of foam-filled ellipse tubes under oblique impact loading
TL;DR: In this paper, a novel foam-filled ellipse tube (FET) is proposed and compared with other hollow and foamfilled tubes with different cross-sections under multiple loading angles, which include square, circle and rectangle.

Energy absorption of an axially crushed square tube with a buckling initiator
Xiong Zhang,Haibin Su,T.X. Yu +2 more
TL;DR: In this paper, a buckling initiator near the impact end of a square tube is proposed to reduce the initial peak force of the square tube while retaining its deformation mode and energy absorption.

Crushing analysis of foam-filled single and bitubal polygonal thin-walled tubes
TL;DR: In this article, the energy absorption characteristics of single and bitubal polygonal tubes with different cross-sectional configurations under different axial crushing load conditions were compared by using the complex proportional assessment (COPRAS) technique.
Journal ArticleDOI
Theoretical prediction and optimization of multi-cell hexagonal tubes under axial crashing
TL;DR: In this article, the analytical formulas of mean crashing force for four different hexagonal tubes with multiple cells were first derived based on the Simplified Super Folding Element (SSFE) theory through several typical constituent elements: corner element, three-panel angular element I and three panel angular element II.

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.
