In this study, numerical and theoretical investigations are carried out to study the crushing
behavior and energy absorption characteristics of bio-inspired hierarchical circular tube …

Thin-walled structures have been widely applied as energy absorption devices due to their
lightweight, high energy dissipating capability through large deformation, and low cost. The …

Under axial loading, the thin-walled structures will experience severe plastic collapse at the
corners. The presented paper focuses on the axial dynamic performances of the thin wall …

This study presents a thorough numerical evaluation of the crashworthiness properties of a
new bio-inspired DNA tubes (BIDNATs) with circular, elliptical, and rectangular cross …

A multi-wall structure by sandwiching star-shaped tube between two circulars is proposed
and named it CSC-tube in this paper. It is found that the interaction effects between tubes …

In this work, a kind of novel sandwich square tube, filling plate-lattice into square tube, was
proposed and preparation by 3D printing. The axial and lateral crushing performances of …

In this paper, multi-objective crashworthiness optimisation of the new multi-corner cross-
section tubes has been studied. The experimental validated Abaqus/ExplicitTM finite …

In the present study crashworthiness performance of monolithic and co-axial multi-wall
(double, triple, and four layered) frusta tube structures was investigated under the quasi …

The thin-walled tubes used in the front rails of the vehicle's body in white play a major role in
absorbing the energy of the collision. In this work, the energy absorption characteristics of …

The quasi-static and dynamic crushing response and the energy absorption characteristics
of combined geometry shells composed of a hemispherical cap and a cylindrical segment …
