Query: On the atomistic energetics of carbon nanotube collapse from AIREBO
  potential   Molecular dynamics simulations based on the adaptive intermolecular reactive
empirical bond order (AIREBO) were performed to probe hydrostatic pressure
induced collapse of single-walled and double-walled carbon nanotubes. It was
unveiled that the torsion term, which is a specific potential component
involved in the AIREBO scheme, plays a vital role in stabilizing fully
collapsed cross-sections of the carbon nanotubes. Evolution of the
cross-sectional deformation along the loading-unloading curve was also
elucidated, showing strong dependence on the presence of a structural defect on
the outer carbon wall.
