• In this article, the vibrational properties of two kinds of single-layered graphene sheets and single-wall carbon nanotubes(SWCNT) are studied. The simulations are carried out for two types of zigzag carbon nanotubes (6,0), (12,0), armchair carbon nanotubes (4,4), (6,6) and zigzag and armchair graphene sheets with free-fixed and fixed-fixed end conditions. Fundamental frequency is determined by means of molecular structural mechanics approach. Results are presented as diagrams stating fundamental frequencies of nanotube and graphene sheet with respect to aspect ratios. The results indicate that fundamental frequency decreases as aspect ratio increases. Fundamental frequency of nanotubes is larger than that of graphene sheets. The results are in good agreement with results of previous researches.
