Axial crushing behavior and energy absorption efficiency of corrugated tubes
TL;DR: In this article, the effect of corrugations on the crushing behavior, energy absorption, and failure mode of circular aluminum tubes was investigated under axial compressive loading, and it was shown that corrugated tubes have a uniform load-displacement curve without an initial peak load.

The Energy-Absorbing Characteristics of Tubular Structures With Geometric and Material Modifications: An Overview
S. Chung Kim Yuen,G.N. Nurick +1 more
TL;DR: In this paper, the axial response of tubular sections with imperfections and fillers subjected to axial impact loads relevant to the field of structural crashworthiness is reviewed. And the types of imperfections discussed include prebuckle, parallel and dished indentations, cutouts, stiffeners, fillers, and wrapping.

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.
Journal ArticleDOI
Extensible plastic collapse of thin-wall frusta as energy absorbers
TL;DR: In this paper, the crumpling of thin-walled frusta, under axial compression, in the ‘concertina’ mode is studied, where the energy expended in bending at the plastic hinges and in stretching the metal between the hinges is minimized for the total decrease in height due to collapse.

The crumpling of steel thin-walled tubes and frusta under axial compression at elevated strain-rates: Some experimental results
TL;DR: In this article, the axial load-deformation or compression behaviour of cylinders and frusta for the two semi-apical angles used, 5° and 10°, were recorded and the modes of collapse were observed and discussed.
Crashworthiness of vehicles
W Johnson,A G Mamalis +1 more
TL;DR: In this article, the authors reviewed information concerning the mechanics of vehicular impact, the plastic deformation which follows and the consequences for vehicle occupants, and how the destructive consequences can be reduced or minimized when a collision occurs.
