This paper investigates energy absorption performance of multi-cell tubes considering the
influence of axial constrain in bending process Firstly, three-point-bending tests and fully …

The lotus petiole in nature is characterized by its porous structure and high bending
resistance. Inspired by this, in this paper, random sampling of lotus petiole was carried out to …

Bionic structures have garnered considerable attention due to their superior energy
absorption capacity and light weight. This study proposes a group of bionic thin-walled tubes …

To improve the energy absorption of traditional structures, impact resistant natural materials
are usually mimicked to develop novel structures with desirable energy absorption. In this …

To improve the energy absorption of the traditional tube, a bionic tube was proposed based
on the structure and mechanical properties of yak horn. The specific energy absorption of …

In this study, two impact tests are performed on a one-fifth scaled parking structure to obtain
their columns' failure modes and response. A numerical model is developed to simulate the …

Curved tubes are widely used on autobody to suffer the transverse bending loads. This
paper studies the energy absorption performance of curved tubes under transverse bending …

Thin-walled structures are widely used as energy absorbers in aircraft and automobiles.
They have a high load-bearing capacity despite their small thickness. Due to their …
