Developing an innovative protective structure with excellent energy absorption performance is a continuous research effort. The emerging additive manufacturing techniques allow fabricating structures complex geometrical shapes which have the potential to yield unprecedented properties. Accordingly, in this paper, crush and behaviour of new designs, namely Concave Tubes (CTs) featuring inwardly ...

Approaches such as changing the cell number, rib direction, and adding internal structure are utilized to acquire a multi-cell thin-walled structure, these approaches have meaningful effects on crashworthiness performance of tubes. In this study, comprehensive review is done by using comparing together under quasi-static three-point bending conditions. A different indicator better for each prod...

The structure and the electronic properties of single-walled zigzag BN and B3C2N3 nanotubes (n, 0; n=4–10) were investigated using first-principles calculations based on a density functional theory. A plane–wave basis set with periodic boundary conditions in conjunction with Vanderbilt ultrasoft pseudo-potential was employed. The energy gap of ZB3C<su...
