| In this paper, a nonlocal beam model is developed and applied to investigate flapwise vibration characteristics of a rotating single-walled carbon nanotube on a Pasternak foundation. Differential quadrature method is used to solve equation of motion. The effects of small-scale factor, angular velocity and elastic foundation on the natural frequencies are examined and discussed. It is shown that small-scale effect plays an important role in the vibration response of a rotating nanotube. |
