“Hyperelastic modelling of post-buckling response in single wall carbon nanotubes under axial compression”, Procedia Engineering, Vol. 10, pp 2256-2261, 2011 (ICM11), DOI: 10.1016/j.proeng.2011.04.373
ABSTRACT: This paper presents a hyperelastic finite element-based lattice approach for the description of post-buckling response in single wall carbon nanotubes (SWCNTs). A one-term incompressible Ogden-type hyperelastic model is adopted to describe the mechanical response of SWCNTs under axial compression. Numerical experiments are carried out and the results are compared to atomistic simulations, demonstrating the predictive capabilities of the present model in capturing post-buckling behaviour and the main deformation mechanisms under large compressive deformations.
