On the crashworthiness performance of thin-walled energy absorbers: Recent advances and future developments
TL;DR: In this article, a comprehensive overview of the recent developments in the area of crashworthiness performance of thin-walled (TW) tubular components is given with a special focus on the topics that emerged in the last ten years such as crashworthiness optimisation design and energy absorbing responses of unconventional TW components including multi-cells tubes, functionally graded thickness tubes and functionally graded foam filled tubes.

On design of multi-cell tubes under axial and oblique impact loads
TL;DR: In this paper, a group of multi-cell tubes with different cell numbers were comprehensively investigated under both axial and oblique loads, and the results showed that different loading angles have different requirements on cell allocation and optimizations of multiple load cases can yield better solutions in a weighted average fashion, whereas the optimization for separate single load cases (SLC) could result in inferior performance under other load cases.

Recent advances in novel metallic honeycomb structure
TL;DR: In this paper, a comprehensive overview on the development of the innovative honeycomb-based structures in the past two decades, including filled-type, embedded, tandem, hierarchical, auxetics with Negative Poisson's Ratio (NPR), etc.

Crashworthiness design for foam filled thin-wall structures
TL;DR: In this article, a multi-objective optimization framework for thin-walled column with aluminum foam-filler was proposed. And the difference between the single-and multipleobjective optimizations was discussed in a Pareto sense and the importance to seek for multiobjective optimisation was highlighted.

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.

Crushing analysis of metal honeycombs
TL;DR: In this article, a method for determining the crushing strength of hexagonal cell structures subjected to axial loading is given, based on energy considerations in conjunction with a minimum principle in plasticity.
