ABSTRACT
We concentrated on evaluating the vibrational response of ideal and defected degenerated
carbon nanostructures under the influence of different boundary conditions. In addition,
an attempt has been made to investigate the relative deviation of the natural frequency of
imperfect systems and to study the effect of defected regions on vibrational stability of the
particles. It has been found that a single and pinhole vacancy defect have the least and the
most impact on the natural frequency of nanostructures. Furthermore, the effect of CNT
diameter on natural frequencies of low-dimensional systems has also been investigated in
this research.
