Low velocity impact of empty and foam filled circumferentially grooved thick-walled circular tubes
TL;DR: In this article, the energy absorption and collapse mode of circumferentially grooved thick-walled tubes are scrutinized analytically and experimentally under dynamic loading condition and the effect of strain rate is incorporated into the equations by implementing the Cowper-Symonds constitutive equation.

Deformation modes and crashworthiness energy absorption of sinusoidally corrugated tubes manufactured by direct metal laser sintering
Sami E. Alkhatib,Mohammad S. Matar,Faris Tarlochan,Othman Laban,Ahmed Saeed Mohamed,Nouman Alqwasmi +5 more
TL;DR: In this article, a sample of 8 sinusoidally corrugated tubes was additively manufactured and tested under a quasi-static displacement rate of 20mm/min, and the results showed that these tubes exhibit lower and stable crushing forces compared to conventional straight tubes.
Journal ArticleDOI
The energy absorption of thin-walled tubes designed by origami approach applied to the ends
TL;DR: In this paper, a novel origami-ending tube (OET) was proposed by introducing some small triangular origami patterns into the ends of the tube module, which greatly simplified the manufacturing process because it did not require welding.

Closed-form solution for crushing response of three-dimensional thin-walled “S” frames with rectangular cross-sections
Heung-Soo Kim,Tomasz Wierzbicki +1 more
TL;DR: In this paper, the results of the biaxial bending collapse of prismatic beams and the collapse under combined bending and compression developed earlier by the present authors were applied to a practical problem of a three-dimensional S frame.

Hybrid metal-composite conical tubes for energy absorption; theoretical development and numerical simulation
Ali Shiravand,Masoud Asgari +1 more
TL;DR: In this article, the effect of various parameters including semi-apical angle, ply pattern of laminated composite, diameter of tube, wall thickness and material properties of tubes on energy absorption capacity and crashworthiness characteristics of various considered specimens are investigated.

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.
