Abstract

Current study concerns the vibrational behavior of single-walled carbon nanotube/graphene junctions using the finite element method. The effects of different parameters including nanotube and graphene geometry/boundary conditions on the vibrations of nanotube/graphene junction are investigated. Two types of junctions are considered. In the first type, the nanotube is connected to one side of graphene, while in the second type, both sides of the graphene are connected to nanotubes. It is shown that increasing the height-to-length ratio of graphene results in decreasing the fundamental natural frequency of the junctions. When the boundary conditions are imposed on the graphene, increasing the radius of carbon nanotube leads to decreasing the frequency. Moreover, the frequencies of the second type models are larger than those of the first type.
