英文摘要	Conference Name:2012 International Conference on Materials Engineering and Automatic Control, ICMEAC 2012. Conference Address: Jinan, China. Time:April 27, 2012 - April 29, 2012.; Control Science and Engineering of Shandong University; Shandong Institute of Automation; Jinan University and Shandong Institute of Materials Sciences; Based on the finite element method (FEM), we study the elastic constants of double-wall carbon nanotubes (DWCNTs). In the models, the Lennard-Jones potential function is used to consider the Van der Waals' force between non-bond atoms from different layers. The variations of the elastic constants with the diameter and the aspect ratio of the internal layer nanotube are investigated systematically. The computational results indicate that for both the armchair and the zigzag DWCNTs, the elastic moduli are generally lower than those of the single-wall carbon nanotubes with the same chirality as the internal and external layers. With the increase of the diameter and the aspect ratio of the internal layer carbon nanotubes, the elastic constant of DWCNTs will fall to a stable value. 漏 (2012) Trans Tech Publications, Switzerland.
