Abstract: This article aims to review the major crashworthiness studies performed on foam filled thin walled structures. Crashworthiness studies are focused to enhancement in energy absorption, simplify the production processes, reduction in weight and material usage. The crashworthiness studies of foam filled tubes are carried out with various shapes such as square, circular, honeycomb etc., amount of foam filled, functionally graded components and materials like aluminium, steels, and composite materials also used. The experimental analyses were done in various loading conditions like quasi-static and dynamic loading. By the process of deformation, the energy absorption parameters of thin-walled structures are analyzed by many of scholars through various methods such as experimental, numerical, simulation and different optimization techniques. In automotive sector most of the crashworthiness research findings are adopted gradually. These types of efforts are very useful to identify the research gaps in the field of crashworthiness studies for future investigation.

Keywords: Crashworthiness, energy absorption, foam filled thin walled structures, functionally-graded components.
