“…Zhou et al (2017) designed the energy-absorbing structure of a crashworthy railway vehicle by combining the characteristics of thin-walled metal structures and aluminium honeycomb structures, and they discussed the safe velocity standard for rail vehicle collisions, which was improved from 25 km/h to 45 km/h by adopting a combined energy-absorbing structure. Hussein et al (2017) Basically, the main challenge in the crashworthiness design and development of subway vehicles is how to find the optimal design of an EAS that can satisfy best the crashworthiness requirements. Optimisation of structural crashworthiness using surrogate models and intelligent algorithms is considered as a research focus in vehicle engineering (Fazilati and Alisadeghi 2016;Yin et al 2013;Forsberg and Nilsson 2005;Yin et al 2014).…”

“…This is because the foam helps to support the energy absorption capability of the structure [22]. It was supported by a study conducted by Hussien et al that found the specific energy absorption of foam-filled structure was higher compared to hollow one [1]. Similar results gained by Yan et al in the study on lateral crushing of polyurethane foam-filled natural flax fabric reinforced epoxy composite tubes [23].…”

“…Part 2 describes the design and experimental procedure, consists of specimen preparation and optimization method of foam-filled structure under quasi-static and dynamic loading. Later, part 3 presents and discusses the experimental results of the structures together with the optimization results and finally the conclusion was describing in part 4 The energy absorption capability must be high and initial peak force should be sufficiently low and the fluctuation should be in controlled manner to avoid the impact from causing injury to the passenger [1]. Uma Devi et al have conducted a simulation study to find an optimum cross sectional shape of a crash box to ensure high capability for energy absorption without crash beads [2].…”

Crash box are the structural part designed to absorb energy during crash and minimize the injury to passengers. Various design of energy absorbers has been introduced to unleash design with the best crashworthiness behavior. Foam-filled structures are one of the promising designs. In this study, foam-filled structure was investigated to increase the energy absorption capability and reduce the initial peak force simultaneously. Since most foam-filled structures tend to absorb more energy with high peak force, optimization of the energy absorbers is significant in obtaining the optimum design. Response surface methodology (RSM) has been dominant technique in crashworthiness optimization mainly because of it provides efficient and accurate solution. This paper focused on the optimization foam-filled columns with respect to thickness of the tube and length of foam to enhance energy absorptions and reduce initial peak force. The optimization results suggested by Design Expert software for impact test is 515.9 J for EA and 134.94kN for IPF value with the column thickness of 2.0mm and foam length of 185mm. For quasi-static test, the optimum solution value for EA and IPF are 864.5J and 88.33kN respectively with column thickness of 1.87mm and foam length of 200mm.

“…Metal and composite honeycomb structures were introduced as a filling core in many studies [199], [226], [227]. A honeycomb-filled tube exhibited improved crashworthiness performance and higher energy absorption measurements than a hollow tube under axial loading [199], [226].…”

“…This is mainly due to the fact that the honeycomb has a lower density than aluminium foam for the same volume and therefore it offers higher strength to weight ratio than aluminium foam. Hussein et al [226], who conducted an experimental investigation on the axial crushing of square aluminium tubes filled with polyurethane foam and/or aluminium honeycomb, founded that a polyurethane foam-filled tube yields higher energy absorption measurements than a honeycomb-filled tube and thus it was concluded that polyurethane foam core is more effective than honeycomb filling.…”

Over the past several decades, a noticeable amount of research efforts has been directed to minimising injuries and death to people inside a structure that is subjected to an impact loading.\ud \ud Thin-walled (TW) tubular components have been widely employed in energy absorbing structures to alleviate the detrimental effects of an impact loading during a collision event and thus enhance the crashworthiness performance of a structure.\ud \ud Comprehensive knowledge of the material properties and the structural behaviour of various TW components under various loading conditions is essential for designing an effective energy absorbing system.\ud \ud In this paper, based on a broad survey of the literature, a comprehensive overview of the recent developments in the area of crashworthiness performance of TW tubes 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.\ud \ud Due to the huge number of studies that analysed and assessed the energy absorption behaviour of various TW components, this paper presents only a review of the crashworthiness behaviour of the components that can be used in vehicles structures including hollow and foam-filled TW tubes under lateral, axial, oblique and bending loading
