A review of advanced materials, structures and deformation modes for adaptive energy dissipation and structural crashworthiness
TL;DR: In this paper , the authors highlight and summarize the extensive research efforts directed towards the development of more advanced, adaptive energy absorbers with tailored mechanical responses and specialized characteristics, including prescribed steady-state loading regimes, load-limiting behavior and multi-to− omnidirectional load bearing capabilities, and active adaptive systems which can readily alter their geometry based upon data collected by external sensors to implement the preferred mechanical response for a given scenario, either before or during an impact event.

Design of thin wall structures for energy absorption applications: Enhancement of crashworthiness due to axial and oblique impact forces
TL;DR: In this article, a computationally aided design process of a thin wall structure subject to dynamic compression in both axial and oblique directions was described, which was further enhanced for better crash performances by investigating the effect of foam filling, increasing the wall thickness and by introducing a trigger mechanism.

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.
