Inward-contracted folding element for thin-walled triangular tubes
Fangfang Sun,Hualin Fan +1 more
TL;DR: In this paper, a new folding element, named as inward-contracted folding element (OCE), was observed, and double zigzags and half-shortened wavelength were observed in the corresponding deformation curve.

Behaviour of a novel stiffener-enhanced steel–concrete–steel sandwich beam subjected to impact loading
TL;DR: In this paper, a stiffener-enhanced steel-concrete-steel (SESCS) sandwich beam was proposed for impact resisting, and the dynamic response of the SESCS sandwich beam under low-velocity impact loading was experimentally, numerically and analytically studied.

Energy Enhancement of Long Cylindrical Tubes with Grooves Subjected to Axial Impact
TL;DR: In this paper, Circumferential grooves are introduced in cylindrical tubes to force the plastic deformation which helps to control the buckling mode, and the results revealed that grooves can stabilize the deformation behaviour and thus the proposed method could be a good candidate as a controllable energy absorption element.

Ductile damage and fracture finite element modelling of elasto-viscoplastic voided materials
TL;DR: In this article, micro-structure void volume fraction is taken into account with finite element models developed for high strain rate elasto-viscoplastic problems, and a radial return algorithm is proposed for the implementation into explicit finite element frameworks.

Interplay of Factors Influencing Collapse Modes in Axially Crushed Tubes
AA Singace,H El-Sobky +1 more
TL;DR: In this paper, the effects of various schemes of end constraints, heat-treatment, filler density and impact velocity on the behavior of axially crushed tubes of different L/D and D/t ratios 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.
