Molecular dynamics simulation was used to study the critical buckling force, pressure and strain of pristine and defected single-walled carbon nanotubes under axial compression. Effects of length, radius, chirality, Stone-Wales defect, and single vacancy defect on buckling behavior of single-walled carbon nanotubes were studied. Obtained results indicate that axial stability of single-walled carbon nanotubes reduced significantly due to topological defects. Critical buckling strain was more susceptible to defects than critical buckling force. Both Stone-Wales and single vacancy defects decrease the buckling mode of single-walled carbon nanotubes. Comparative approach of this study led to more reliable design of nanostructures.
