On design of graded honeycomb filler and tubal wall thickness for multiple load cases
TL;DR: In this article, a double functionally graded (DFG) structure was introduced, which comprises of a functionally graded honeycomb filler in a functional graded thickness (FGT) tube, and the comparison of deformation modes and critical crushing angles clearly indicated that the DFG structure is of better and more stable crashing characteristics, being a crashworthy structure.

Crashworthiness analysis and optimization of fourier varying section tubes
TL;DR: In this paper, the authors used Fourier series expansion to generate a series of novel sectional configurations, namely Fourier varying sectional tubes (FVSTs), to look into their advantages of crashworthiness.
Journal ArticleDOI
Numerical simulation of the axial collapse of thin-walled polygonal section tubes
TL;DR: In this paper, the post-buckling deformation of aluminum alloy extruded polygonal section tubes subjected to dynamic axial impacts was investigated using finite element code LS-DYNA, which is the primary analytical tool used in this investigation.

Nondeterministic optimization of tapered sandwich column for crashworthiness
TL;DR: In this article, a reliability based design optimization (RBDO) is adopted to consider the uncertainties of design variables and noise factors in crashworthiness optimization for the foam-filled bitubal tapered structure.
Journal ArticleDOI
Nonlinear finite element analysis of the crush behaviour of functionally graded foam-filled columns
TL;DR: In this paper, the effect of density grading, number of grading layers, and thickness of the interactive layer upon the resulting specific energy absorption was investigated, and the results showed relative improvement of 12% in energy absorption levels of density-graded foam-filled structures over their uniform density counterparts with the same mass.

Dynamic axial crushing of square tubes

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.
