Topological configuration analysis and design for foam filled multi-cell tubes
TL;DR: In this article, the effects of cross-sectional configurations, including topological distribution of empty and foam-filler in the multi-cell tube, on the crashworthiness, and further optimizing the wall thickness and foam density were explored.

Crushing analysis and multiobjective optimization for functionally graded foam-filled tubes under multiple load cases
Guangyao Li,Zheshuo Zhang,Guangyong Sun,Guangyong Sun,Fengxiang Xu,Xiaodong Huang,Xiaodong Huang +6 more
TL;DR: In this article, the authors investigated the crashworthiness of the FGF-filled square tubes under multiple load cases, and they found that the foam density varies along the axial direction and is controlled by the gradient exponent.
Journal ArticleDOI
Multiobjective crashworthiness optimization of hollow and conical tubes for multiple load cases
TL;DR: In this paper, a multi-objective optimization method was proposed to understand and optimize the dynamic responses and energy absorption of foam-filled conical thin-walled tubes under oblique impact loading conditions.

A comparative study on the windowed and multi-cell square tubes under axial and oblique loading
Jie Song,Fenglin Guo +1 more
TL;DR: In this article, a comparative study on the performance of windowed and multi-cell square tubes of the same weight under axial and oblique loading is conducted numerically, and the results show that the multicell tube can achieve higher mean crushing force than the windowed tube but the window-ed tube has lower initial peak force.

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.
