A circular DLGS with an eccentric hole and upper and lower surface layers is depicted in Fig. 1. The graphene sheet's geometric properties are denoted by inside radius R2, outside radius R1, eccentricity ε, and thickness h. The elastic modulus, Poisson's ratio and mass density of the bulk part of DLGS are respectively indicated by E, v and ρ. The parameters λ and μ indicate the classical Lame constants while the surface Lame constants are shown by λ^s and μ^s. τ^s is the surface residual stress which is uniformly distributed on the upper and lower surfaces of the DLGS. The surface mass density and the surface elastic modulus of the DLGS are also indicated by ρ^s and E^s, respectively. To interpret mathematical formulations, two polar coordinates (r1, θ1) and (r2, θ2) are taken to coincide with the center of the outer and inner circles, respectively. The upper and lower surfaces of the DLGS at z = ±h/2 are denoted by s^+ and s^-, respectively.
