On the stability characteristics of zigzag phosphorene nanotubes: A finite element investigation

Abstract

This paper aims to investigate the mechanical properties of zigzag phosphorene nanotubes under the compressive loading. To this end, a finite element model is used whose elemental properties are computed by simulating the P[sbnd]P bonds in the structure of the phosphorene nanotubes by beam elements. It is shown that the critical compressive force of zigzag phosphorene nanotubes is significantly smaller than that of the single-walled carbon nanotubes with the same size and boundary conditions. By investigating the effect of aspect ratio and radius on the compressive characteristics of the phosphorene nanotubes, it is represented that the critical compressive force has an inverse and direct relation with the former and latter geometrical parameter, respectively. © 2017 Elsevier B.V.
