Many studies have focused on the topic of vehicle safety, including the study on
crashworthiness. In vehicle, a crash box structure is an integral component for ensuring the …

Previous studies have shown that the multi-cell bi-tubular tubes exhibit superior energy
absorption compared to the multi-cell tubes. To further improve the energy absorption of the …

In order to improve the crashworthiness and energy absorption of thin-walled tubes, this
work proposes a novel design inspired by the vascular fiber sheath flap (VF) and central …

Hierarchical design and gradient design have been shown to improve the crashworthiness
of structures. However, fewer studies combine the two. Therefore, this study combines the …

The optimization of foam-filled crash boxes is desired to enhance the energy-absorbing
capacity of frontal crash management systems and improve vehicle crash safety. A novel …

Recently, bionic thin-walled structures have attracted widespread attention in automotive
safety design because of their excellent crashworthiness behavior and weight efficiency. In …

The effect of inducing circular holes into aluminum wrapped with glass/epoxy (Al/GFRP)
pipes was investigated. Intact and holed specimens were evaluated in quasi-static axial …

This paper aims to investigate quasi-static and low-velocity impact responses of three
manufactured bio-inspired hybrid multi-cell aluminum and polypropylene (Al/PP) sandwich …

The crashworthiness performance and the deformation history of glass fiber reinforced
epoxy (GFRP) composite over wrapped aluminum (Al) cylinders with induced holes were …

Thin-walled metal structures are known as an effective solution in absorbing impact energy
and reducing the resulting reaction forces. The design of energy absorbers with higher …
