Energy absorption of riveted structures
TL;DR: In this article, a basic research program has been undertaken, in co-operation with AGUSTA Helicopters, covering experimental and numerical activities, to study the crash behaviour and the energy absorption capability of subfloor riveted structural sub-components.

Development of simplified dynamic models using optimization: Application to crushed tubes
Changhwan Kim,Jasbir S. Arora +1 more
TL;DR: In this article, an axially crushed tube is simplified to a single degree of freedom lumped mass model whose motion is resisted by nonlinear force elements, and the crushing behavior is captured in the force-displacement curve for the force elements.

Uniaxial crushing of constrained tubes
A A Singace,H El-Sobky +1 more
TL;DR: In this article, the behaviour of mild steel and aluminium alloy tubes of relatively low D/t ratio, subjected to an axial crushing load, is studied and different combinations of end constraints were produced by radially constraining one or both ends of the loaded tube outwards, inwards, or in both directions.

Multi-objective optimization of a tapered elliptical tube under oblique impact loading:
TL;DR: In this article, a single-cell tapered elliptical tube with different configurations and different cross-sections (square, rectangular, and circular) was proposed to determine the crashworthiness performance at multiple loading angles.

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.
