In this project, fully generalised analytical expressions for longitudinal Young’s modulus are developed for zigzag Single-Walled Nanotubes (SWNTs), based on a hexagonal honeycomb motif, using an energy equivalent approach. Honeycomb geometry (bond lengths and angles), and bond-stretch and bond-angle force constants are considered as variable parameters and deformation is assumed due to simultaneous bond stretching and bond angle variation in response to an applied axial load. A parametric study is then performed to explore the structure-property relationships in auxetic (negative Poisson’s ratio) nanotube.
