Energy absorption characteristics of aluminium alloy AA7XXX and AA6061 tubes subjected to static and dynamic axial load
TL;DR: In this paper, compression behavior and energy absorption of aluminium alloy AA7005 and AA7003 tubes were investigated both experimentally and numerically using LS-DYNA software.

On the layered micromechanical three-dimensional finite element modelling of foam-filled columns
TL;DR: In this article, a micromechanical layered model is proposed for the finite element analysis of the quasi-static collapse of foam-filled ultralight aluminium box sections, which allows for the local penetration of the folds and shearing of the foam, thus avoiding the commonly adopted approximations in which the foam must undergo global deformation to accommodate the externally applied loads.

Crush behavior optimization of multi-tubes filled by functionally graded foam
Omid Mohammadiha,H. Ghariblu +1 more
TL;DR: In this paper, the energy absorption of FGF-filled multi-tubes is higher than their equivalent multitubes filled by uniform foams, and the results show that the type of function employed for grading foam has significant effect on their crush response.

Axial crush behaviours and energy absorption characteristics of aluminium and E-glass/epoxy over-wrapped aluminium conical frusta under low velocity impact loading
M. Kathiresan,K. Manisekar +1 more
TL;DR: In this paper, low velocity axial impact crush behaviors and energy absorption characteristics of thin-walled aluminium conical (AC) and E-glass/epoxy composite over-wrapped aluminum conical hybrid frustrated shells (CWAC) have been studied through experimental and numerical procedures.

The energy absorption of rectangular and slotted windowed tubes under axial crushing
TL;DR: In this paper, rectangular and slotted windows were introduced to thin-walled square tubes to improve the crashworthiness of tubular structures to reduce the initial peak load and increase the crush force efficiency.

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.
