Modeling instability of carbon nanotubes: from continuum mechanics to molecular dynamics
A comprehensive continuum mechanics and molecular mechanics model is developed to predict the critical strain, stress, and buckling load of the inelastic buckling of carbon nanotubes. With the proposed model, the beam- and shell-like buckling behavior of carbon nanotubes can be analyzed. The existence of the optimum diameter, at which the buckling load reaches its maximum, is uncovered by the model. The simplicity and effectiveness of the proposed model are not only able to reveal the chiral and size-dependent buckling solutions for carbon nanotubes, but also enable a thorough understanding of the stability behavior of carbon nanotubes in potential applications.
