TLDR
In this paper, a series of over 120 axial crushing tests were conducted on circular and square steel tubes loaded either statically or dynamically, and approximate theoretical predictions for static and dynamic progressive buckling were developed.About:

Multi cornered thin wall sections for crashworthiness and occupant protection
TL;DR: The desire to improve crashworthiness of a passenger vehicle for enhanced occupant safety has been a major challenge for decades as mentioned in this paper, and when a crash is unavoidable, it is the crash energy and the manner in which vehicle occupants experience the associated force

Mechanical behavior of Ti–6Al–4V lattice-walled tubes under uniaxial compression
TL;DR: In this paper, a finite element software LS-DYNA is used to simulate the structure established by the beam element, and the critical impact velocity is obtained when the structure collapses layer by layer.
Dissertation
Impact energy absorption analysis of different thin-walled tubes with and without reinforcement
TL;DR: In this article, a multi-cell thin-walled tube with different lengths and dented grooves has been investigated to achieve higher energy absorbing efficiency, and a new multicell profile which is composed of coaxial tubes had been proposed.
Journal ArticleDOI
Comparative study on thin-walled structures with function graded strength and tapered angle
TL;DR: In this paper, the crashworthiness characteristics of straight functionally graded strength (SFGS), TUS and classical straight uniform strength (SUS) tubes under axiomatic crashworthiness tests were compared.

On the lateral collapse of an identical pair of cylinders
TL;DR: In this article, a simple mathematical model is proposed to describe the mechanical behavior of these structures, simulating the dynamic lateral compression of rate-sensitive metallic cylinders as related to their use in an energy absorbing device.

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.
