This paper concerned with the study of the effect of thermo-elastic damping on transverse waves propagating in a single-wall carbon nanotube. The Q-factor for thermo-elastic damping is investigated for transverse wave propagating in the nanotube. As a physical model, cylindrical shell is considered and the Donnell-Mushtari-Vlasov approach is applied. The influences of the room temperature and radial thickness of the nanotube on the vibration behaviors are discussed. The effects of the room temperature and radial thickness of the nanotube on the quality factor are examined numerically. It can be shown that the Q-factor is proportional to the radial thickness of the nanotube. On the other hand, the opposite trend is appeared with the change of room temperature. It means that the Q-factor for a single-wall carbon nanotube decreases with the increase of the room temperatures. |
