“…In this part, we present numerical results of vibration of the clamped-clamped (-C), simply supported-simply supported (SS-SS) and clamped-simply supported (C-SS) three-layred nanobeam. The three-layred nanobeam is made of bilayer Graphene nanoribbon (BLGNR) with the following material properties ρ = 2260 kg m −3 , G = 4.6 GPa and E = 1.06 TPa (Nazemnezhad et al, 2014) and (Hosseini Kordkheili et al, 2013). The effects of the dimensionless nonlocal parameter µ on vibration frequencies and deflection mode shapes under different boundary conditions are discussed.…”

In this paper, the first investigation on free vibration analysis of three-layered nanobeams with the shear effect incorporated in the mid-layer based on the nonlocal theory and both Euler Bernoulli and Timoshenko beams theories is presented. Hamilton's formulation is applied to derive governing equations and edge conditions. In order to solve differential equations of motions and to determine natural frequencies of the proposed three-layered nanobeams with different boundary conditions, the generalized differential quadrature (GDQM) is used. The effect of the nanoscale parameter on the natural frequencies and deflection modes shapes of the three layered-nanobeams is discussed. It appears that the nonlocal effect is important for the natural frequencies of the nanobeams. The results can be pertinent to the design and application of MEMS and NEMS.

“…These weak vdWs forces make interlayer Young's and shear moduli for MLGNRs [1,[10][11][12][13][14][15][16]. Accordingly, these interlayer moduli induce considerable changes in electrical and mechanical properties of MLGNRs in comparison with a monolayer GNR [1,4]. Therefore, it is necessary to consider the interlayer moduli effects of vdWs interactions when the mechanical behaviour analysis of MLGNRs is desired.…”
