AB The Membrane stiffness, Young's moduli, Poisson's ratio and eigenfrequencies are investigated in this paper. Graphene sheet is modelled by beam elements. The properties of these elements are directly derived from interatomic potentials. Graphene sheet is modelled with commercial finite element code and the boundary conditions are applied in two different directions. From these simulations the membrane stiffness C, Young's modulus Y and the Poisson's ratio μ of the graphene sheets are obtained. Then the first twenty eigenfrequencies of the graphene sheets are investigated.
