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

Taking advantage of multi-cell tubes and lattice structures on improving crashworthiness
performances, a novel multi-cell thin-walled tube filled with uniform and graded lattice …

In order to improve the energy absorption capacity of the honeycomb, a combined auxetic
honeycomb is designed in this paper. By using the double-inclined walls replacing the …

Deformation instability is a macroscopic and microscopic phenomenon of non-uniformity
and unstable deformation of materials under stress loading conditions, and it is affected by …

To address the limitation of inflexible dimension parameters in thin-walled structures for
ensuring energy absorption effectiveness, a design approach for a multi-tube combination of …

The response characteristics of large-scale structures subjected to impact loading can in
principle be determined by scaled experiments. Unfortunately, scaling suffers from scale …

This paper proposes a novel nested corrugated-elliptical tube (NCET) system as an energy
absorber. The crushing characteristics of the NCET are investigated under lateral load …

A circular–triangular nested tube (CTNT) was proposed for dissipating impact or blast
energy. Experimental studies on CTNT energy absorbers under a lateral quasi-static …

Beetle's elytra provide elaborate microstructural designs to achieve functional synergies in
face of external environments. Natural design strategies can provide effective solutions to …

The force-displacement curve of the energy absorbing structure is generally divided into
three stages. And the stable plateau force is important for the energy absorption device. The …
