Abstract

In the present study, the effects of arrangement and distribution of multifarious types of defects on fundamental frequency of CARBON NANOTUBEs are investigated with respect to different chirality and boundary conditions. Interatomic interactions between each pair of carbon atoms are modeled using two types of NON-LINEAR SPRING-like elements. To obtain more information about the influences of defects, the effects of location, number and distribution (gathered or scattered defects) of two most common types of defects (vacancy and STONE-WALES DEFECTs) are examined on vibrational behavior of CARBON NANOTUBEs. Obtained results are in good agreement with the results reported in other literature. The results show that, gathered VACANCY DEFECTs cause to a reduction in NATURAL FREQUENCY of nanotubes, especially in the case of fix-fix boundary condition. It is also observed that the effect of defects depends on chirality intensively. In addition, the influence of the first VACANCY DEFECT is significantly more than the first STONE-WALES DEFECT.
