Modal analysis of carbon nanotubes and nanocones using FEM

► Modal analysis of SWCNTs and SWCNCs was performed using a FEM with ANSYS. ► The SWCNTs and SWCNCs were modeled using three-dimensional elastic beams. ► The natural frequency of SWCNTs decreases with increasing ellipse ratio. ► The natural frequencies of the SWCNCs increased significantly at higher modes of vibration.
