Abstract

Effect of one atomic vacancy on buckling of single-walled carbon nanotubes is studied through an elastic beam model in the paper. The nature of the vacancy is modeled by a portion of reduced moment of inertia of cross section for the nanotube beam structure, and the size of the atomic vacancy in both zigzag and armchair nanotubes is investigated through a minimization process by molecular mechanics. The critical buckling strain of the defected carbon nanotubes with different boundary conditions is derived and the effect of location of the single vacancy is investigated as well through numerical simulations.
