Thin-walled hollow structures capable of large plastic deformations are ubiquitously present
in sacrificial, high-capacity energy absorbers. A significant challenge in the field of structural …

Helicopters are versatile aircraft that can perform numerous missions such as ground
surveillance, rescue missions, air ambulance, fire-fighting etc. However, helicopter crashes …

In order to enhance the load-carrying and energy-absorbing capacity of the energy-
absorbing structure, a new energy-absorbing mode of a metal foam-filled sandwich circular …

A novel bio-inspired multicell tube (named UCGS), mimicking the unique double-diagonally
reinforced configuration in the unit cell of glass sponge (GS), was proposed and fabricated …

The choice for a proper external trigger and fiber hybridization configuration has a significant
impact on the stability of the crushing process and material cost for composite structures in …

In recent years, hierarchical structures were popularly investigated due to its significant
promotion on structural strength and stiffness. In this study, the concept of vertex-based …

Energy absorption of traditional tubular energy absorbers is restricted by the low structure
efficiency, which makes the mean crushing force of the structure usually much lower than its …

This study first developed a novel bamboo-inspired foam-filled tube (BFFT) for potential
application in high-speed trains, considering the practical use conditions. The BFFT was …

A structure of circular tubes subjected to radial extrusion with variable geometrical
configurations was analysed. In a quasi-static experiment, axial grooves were produced on …

The expansion tube plays a crucial role in the field of train collision safety protection. In this
study, we combine the expansion characteristics of negative Poisson's ratio (NPR) with the …
