▎ 摘　　要

This article mainly uses a structural mechanics approach to analyze the elastic properties of a single-layered graphene sheet (SLGS). Besides, the space frame structure is also adopted to model the interatomic forces of the carbon-carbon bonds. By means of the finite element method, the elastic properties of SLGS on the basis of different chirality and size are measured. According to the results, the elastic properties of SLGS are size- and chirality-dependent, which is in consensus with the literature.
