Abstract:
This paper utilizes atomistic-continuum mechanics method (ACM) to investigate the mechanical properties of single-walled carbon nanotubes (SWCNTs). Fundamental to the proposed concept is the perception that a carbon nanotube is a geometrical frame-like structure, and the potential energy between carbon atoms is equivalent to atomistic-continuum transformation elements by specific potential function and finite element method (FEM). By establishing a linkage between structural mechanics and molecular mechanics, the Young’s moduli of single-walled carbon nanotubes are obtained. According to atomistic-continuum mechanics method and finite element method, an effective atomistic-continuum model is demanded to investigate Young’s moduli of single-walled carbon nanotubes with affordable computational time by personal computer.
