Abstract

In this paper, molecular dynamics simulation is carried out to investigate the mechanical properties and dynamic behaviors of carbon nanotubes with vacancies and related defects. We have shown the Yang´s modulus and tensile strength of nanotubes with vacancy-related defects are dependent on the characteristics of vacancies. Meanwhile, the phonon density of state (DOS) are used to study the vibration properties of carbon nanotubes of various types. and further determine the dynamical behavior of carbon nanotubes under different tensile strains.
