Abstract
This paper utilizes the atomistic-continuum mechanics method (ACM) [1-2] to investigate the mechanical properties of single-walled carbon nanotubes (SWCNTs). By establishing a linkage between structural mechanics and molecular mechanics, the Young's moduli of single-walled carbon nanotubes are obtained. In addition, according to the atomistic-continuum mechanics and the finite element methods, an effective atomistic-continuum model is required to investigate Young's moduli of single-walled carbon nanotubes with an affordable computational time by means of personal computers. The validity of the results is demonstrated by comparing them with existing results.
