摘要：

The paper studies a buckling behaviour of simply-simply supported single-walled carbon nanotubes (SWCNTs) without and with defects. The buckling of carbon nanotubes without and with defects was investigated by the finite element method (FEM). The carbon nanotubes were modelled as beams. The defects were created by removing of randomly determined carbon atoms and beam elements connected to these nodes. The increasing number of defects leads to the decrease of the critical buckling force of SWCNTs. The decrease of the critical buckling force was almost the same for SWCNTs with the same diameter but a different chirality.
