▎ 摘　　要

The shear and tensile-compressive effects of van der Waals (vdWs) bindings on the nonlocal vibrational behavior of bilayer graphene nanoribbons (BLGNRs) are simultaneously investigated in the present study. To idealize the structure of BLGNRs incorporating interlayer shear and tensile-compressive influences, a nonlocal sandwich beam (NSB) theory is employed to model the nanoribbon layers as faces and vdWs interactions as core of the NSB. The effects of interlayer moduli are investigated on the first four nonlocal natural frequencies of BLGNRs for various nonlocal parameters, considering that the small-scale effect causes mode shapes involving tensile-compressive effect of vdWs interactions be excited later.
