Application of kinematic models to compression and bending in simplified crash calculations
TL;DR: In this paper, a compression bending kinematic model was developed to determine the resistance to collapse of thin-walled structures of simple geometry subjected to compression or bending loading, using an example of an S-frame undergoing a collision against a rigid block.

Analysis of circular tubes with rectangular multi-cell insert under oblique impact loads
TL;DR: In this article, the authors focused on the analysis of the collapse mode of circular tubes with multi-cell insert under oblique loads and proposed an analytical solution for the evaluation of the crushing force.

Shun Yi Jin,William Altenhof +1 more
TL;DR: In this paper, a quasi-static compressive testing of extruded aluminum alloy AA6061-T6 round and square cross-sectional tubular specimens was completed to investigate the crush characteristics of these structural members under a cutting deformation mode by using a specially designed cutting tool.

Investigation of lateral crushing behaviors of hierarchical quadrangular thin-walled tubular structures
Yonghao Luo,Hualin Fan +1 more
TL;DR: In this article, the authors proposed hierarchical quadrangular tubes (HQTs) with multi-cellular structure and sandwich cellular walls to increase the energy absorbing ability of tubular structures without increasing the weight.

Experimental analysis on the axial crushing and energy absorption characteristics of novel hybrid aluminium/composite-capped cylindrical tubular structures:
TL;DR: In recent years, aluminium-composite hybrid tubular structures, which combine the stable and progressive plastic deformation of the aluminium metal with light-weight composite materials, are obtainable as mentioned in this paper.

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.
