Thermal vibration of double-walled carbon nanotubes predicted via double-Euler-beam model and molecular dynamics
Lifeng Wang, Haiyan Hu
Abstract: The paper presents how to study the thermal vibration of a double-walled carbon nanotube (DWCNT) by using a model of double-Euler-beams, together with the law of energy equipartition, with the energy of van der Waals interaction between layers taken into consideration. The basic finding of the study is the relation, derived via the model of double-Euler-beams and the law of energy equipartition, between the temperature and the Root-of-Mean-Squared (RMS) amplitude of the thermal vibration at any cross section of the DWCNT. The molecular dynamics simulations of thermal vibration of DWCNT in Argon atoms atmosphere show that the model of double-Euler-beams can predict the RMS amplitude of the thermal vibration of DWCNT reasonably well.
