▎ 摘　　要

Since the discovery of graphene in stable state (2004), these nanostructures have been actively used in nanotechnology. The determination of natural frequencies, mode shapes, critical compressing loads, and buckling modes of these sheets is of great theoretical and practical importance for estimating their working characteristics. To this end, in the present paper we apply the method of molecular mechanics, which was used in the authors' earlier studies to solve the problems of natural vibrations, stability, and contact for carbon nanotubes.
