Defect nucleation in carbon nanotubes under tension and torsion: Stone–Wales transformation

We have developed a hybrid continuum/atomistic model to study Stone–Wales transformation in single wall carbon nanotubes. The atoms far away from the defect are characterized by an atomistic-based continuum theory established from the interatomic potential, while atom positions in the vicinity of the defect are determined by molecular mechanics coupled with the atomistic-based continuum theory. For a carbon nanotube in tension, the hybrid …
