Numerical Simulation of The Mechanical Properties of Carbon Nanotube Using the Atomistic-Continuum Mechanics

This paper the utilizes atomistic-continuum mechanics (ACM) to investigate the mechanical properties of single-walled carbon nanotubes (SWCNTs). By establishing a linkage between structural mechanics and molecular mechanics, not only the Young's moduli could be obtained but also the modal analysis could be achieved. In addition, according to atomistic-continuum mechanics and finite element method, an effective atomistic-continuum model is constructed to investigate the above two mechanical properties of SWCNTs with affordable computational time by personal computers. The validity of the results is demonstrated by comparing them with existing results.
