摘要：

An atomic-scale finite element model is employed to study the mechanical vibration frequency shift of armchair and zigzag Single-Walled Carbon Nanotubes (SWCNT) under axial load. Tersoff-Brenner potential is used to define the interactions between the atoms as well as the mechanical properties of the elements in the model. The fundamental frequencies corresponding to the transverse and radial vibration modes of strained SWCNTs increase under compression load, yet they decrease under stretching load. The frequency sensitivities of nanotubes with different diameters and lengths are also investigated. The influence of size effect, curvature effect and the boundary condition are discussed.
