Energy absorption of riveted structures
TL;DR: In this paper, 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.
Journal ArticleDOI
Review of the crushing response of collapsible tubular structures
TL;DR: In this article, a comprehensive analysis of the important findings of extensive research on understanding the crushing response of thin-walled tubular structures is presented, focusing on their energy absorption ability.
Energy absorption of foam-filled steel extrusion under quasi- static oblique loading
Al Emran Ismail,Tun Hussein +1 more
TL;DR: In this article, polyurethane foams with different densities are filled into steel extrusion tubes and the foam-filled structures are compressed quasi-statically at constant cross-head displacement at 10mm/min.

An analytical study for global buckling of circular tubes under axial and oblique compression
Wei Wang,Xinming Qiu +1 more
TL;DR: In this article, an analytical model was proposed for global buckling circular tubes of low diameter-to-thickness ratio (25 D / t 40 ) and moderate length (7 L / D 8 ), based on experimental observations and numerical simulations.

Parametric design of multi-cell thin-walled structures for improved crashworthiness with stable progressive buckling mode
TL;DR: In this article, a new five-cell cross-section that merges high performance multi-cell and twelve-edge cross-sections from previous research was presented, and compared its performance to four-and nine-cell square crosssections.

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.
