Abstract
Aiming at the difficulties of measurement and simulation for small diameter single-wall carbon nanotube (SWCNT), molecular-mechanics theory associated with finite element analysis is adopted to investigate the Young's modulus, 3-D finite element models of armchair, zigzag and chiral nanotubes are established on the ANSYS software platform. With the pure axis loading on the molecular of SWCNT, the Young's modulus is obtained considering the tube diameter and chirality. The influence of the diameter and chirality on the Young's modulus of the SWCNT is discussed. The value of the Young's modulus is found to vary from 0.9 to 1.14 TPa showing a trend of increasing with tube diameter and chirality, and the size effect in small diameter.
