“…Fig. 3 Folding patterns of box-shaped tubes under axial crushing [13,15] Through the combination of two element types, the crushing mode of box-shaped tubes can be divided into three types: extended collapse mode, symmetrical collapse mode, and asymmetric mixed collapse mode [13] . The elements of the four tube corners in the extended collapse mode all present the folding type of Type I, while all four tube corners extend outward in the tube segment, as shown in Figure 3(a); The symmetrical collapse mode is manifested as a Type II folding element in all four angles of the tube segment, in which the folding flap of the box-shaped tube is stacked in an orderly manner, and the inner concave and outer convex lobes are symmetrical with the axis of the section, as can be seen in Figure 3(b).…”

Thin-walled box-shaped tubes, which feature good energy absorption and have a wide range of applications, can be flexibly combined with various buffer materials to form a combined energy consumption structure; However, in view of the complexity of the buffer forms when subjected to axial compression, there is still much room for intensive study in the calculation of the folding method, energy consumption and average force of the tube body during axial crushing. Based on the folding mode and spatial buckling behavior theory of box-shaped tube under axial compression, it not only sorts out the literature on the establishment and improvement process of super-folding theory, but also makes a comparison and analysis of the advantages and disadvantages of the classical method in the calculation of critical buckling force of box-shaped tubes. Moreover, it gives an overview on the common application methods of tube engineering and theoretical progress in terms of the application of box-shaped tubes, as well as makes a summary of the prospect and improvement of box section tube application in civil engineering at the end in this paper.

“…For reducing the initial peak load and increasing the effective deformation stroke, another new solution has been proposed using triggers and cut-outs as imperfections in thin-walled tubes [23]. Moreover, a new non-conventional solution has been developed using circular and square thin-walled tubes loaded under quasi-static and dynamic strain rates [24][25][26][27][28]. The concept is to create a combined biaxial compression-torsion loading within the tested tube via an external uniaxial loading.…”

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
