This letter presents a study of the mechanisms of nonlocal effect on the transverse vibration of two-dimensional (2D) nanoplates, e. g., monolayer layer graphene and boron-nitride sheets. It is found that such a nonlocal effect stems from a distributed transverse force due to (1) the curvature change in the nanoplates and (2) the surface stress due to the nonlocal atom-atom interaction. A single equivalent vibration wavelength is defined to measure the nonlocal effect on the vibration of 2D nanoplates. The critical equivalent wavelength of order 0.55 to 2.23 nm is obtained for significant nonlocal effect on monolayer graphene.
