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.

Crashworthiness analysis and design of multi-cell hexagonal columns under multiple loading cases
TL;DR: In this article, the effects of multi-cell configurations and oblique loads on the crashworthiness performance have been under studied and it is found that for the same cell number, the number of corners plays a significant role in enhancing energy absorption.

Collapsible impact energy absorbers: an overview
TL;DR: In this article, the common shapes of collapsible energy absorbers and different modes of deformation of the most common ones are reviewed, such as axial crushing, lateral indentation, lateral flattening, inversion and splitting, while noncollapsible systems such as lead extrusions or tube expansions are considered to be beyond the scope of this review.
