Nanomechanics on the deformation of single- and multi-walled carbon nanotubes under radial pressure

In this paper, the deformation of single- and multi-walled carbon nanotubes under radial pressure has been studied by using an analytical molecular structural mechanics model. The elastic in-plane properties (in-plane stiffness in the hoop direction, Yθ) and Poisson's ratio (vθz) of single-walled carbon nanotubes (SWCNTs) has been derived and shown to be equal to the axial direction in-plane properties (Yz, vzθ) for all tube diameters. In-plane...
