Investigation of the vibrational characteristics of double-walled carbon nanotubes/double-layered graphene sheets using the finite element method

摘要

This article concerns the investigation of the vibrational behavior of double-walled carbon nanotubes/double- layered graphene sheets junctions using the finite element method. The bonds and atoms are modeled by beam and mass elements, respectively. Moreover, the van der Waals interactions are simulated by spring elements. The effects of the length of the nanotube and the dimensions of the nanosheet on the natural frequencies of the junctions are examined. It is shown that when the boundary conditions are applied on the nanotube, the geometrical parameters of nanotubes have a significant effect on the vibrational behavior of the junctions.
