“…In addition to fuel e ciency and reducing gas emissions, the need for lightweight, high-strength and cost-effective energy-absorbing structures to increase crash safety is increasing. In order to meet these needs, thin-walled structures with different cross-sectional geometries, made of cellular/foam lled [1]- [4] metal [5]-[8] and composite material [9], [10] are widely used in the industry. In addition to some superior properties of metal and composite materials, they also have disadvantages that limit their potential application areas.…”

Hybrid structures attract attention because they eliminate the disadvantages of composite and metal materials and have many potential applications. In this study, the energy absorption performances of single, double and triple hybrid tubes formed from different materials as metal/metal and metal/composite were examined experimentally and numerically. The hybrid tubes were lled with ve different functional aluminum foams of different densities to improve their energy-absorbing performance. Multi-objective optimization (MOO) studies were carried out to obtain the highest speci c energy absorption (SEA) and the lowest peak force con guration for each of the single, double and triple hybrid tubes. In MOO studies, functional foam densities (500-1500 kg/m 3 ) and wall thicknesses (1-4 mm) were optimized by genetic algorithm. As a result, absorbed energy (AE) and SEA values of hybrid tubes with optimum foam densities and wall thicknesses increased.

“…Thin-walled box section tubes, which have suitable cushioning strength and high specific energy absorption because of its stability of energy consumption during axial crushing, are often made into various buffer devices to play the role of energy consumption and material enclosure. Not only can it independently form an efficient energy dissipation absorber, but also can combine with other energy consumption structures to form multilevel and multiform energy consumption systems [1][2][3][4] . Box-shaped tubes show different crushing patterns due to the constraints of adjacent sheets, as well as the width-thickness ratio and aspect ratio during axial crushing.…”

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.
