Theoretical prediction and numerical simulation of multi-cell square thin-walled structures
TL;DR: Based on the Super Folding Element theory, a theoretical solution for the mean crushing force of multi-cell sections were derived by dividing the profile into three parts: corner, crisscross, and T-shape as discussed by the authors.

Transition from initial global bending to progressive buckling of tubes loaded statically and dynamically
W. Abramowicz,Norman Jones +1 more
TL;DR: In this paper, an experimental study was conducted on the static and dynamic axial crushing of 128 thin-walled mild steel columns which buckled mostly in the plastic range. But the results showed that even relatively short columns buckled in the global inelastic buckling mode, while a transition to progressive plastic buckling is observed later in the collapse process.

Crashing analysis and multiobjective optimization for thin-walled structures with functionally graded thickness
TL;DR: In this paper, the effect of different thickness gradient patterns on crashworthiness of thin-walled structures with changing wall thickness along the longitudinal direction in a certain gradient has been investigated, and the results yielded from the optimization indicate that the FGT tube is superior to its uniform thickness counterparts in overall crashing behaviors.

Experimental and numerical investigation of static and dynamic axial crushing of circular aluminum tubes
D. Al Galib,A. Limam +1 more
TL;DR: In this article, a comprehensive experimental and numerical study of the crash behavior of circular aluminum tubes undergoing axial compressive loading is performed, where non-linear finite element analyses are carried out to simulate quasi-static and dynamic test conditions.

Comparative analysis of energy absorption capacity of simple and multi-cell thin-walled tubes with triangular, square, hexagonal and octagonal sections
A. Alavi Nia,M. Parsapour +1 more
TL;DR: In this paper, simple and multi-cell thin-walled tubes made from aluminum with triangular, square, hexagonal and octagonal sections were subjected to quasi-static loading and the experimental results were then compared with numerical simulations.

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.
