ON THE EIGENMODES AND EIGENFREQUENCIES OF LOW-DIMENSIONAL DEGENERATED CARBON STRUCTURES: OBTAINING NATURAL FREQUENCIES OF IDEAL AND STRUCTURALLY DEFECTED SYSTEMS

摘要

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.
