Abstract

This study used a modified orthotropic elastic shell model to study the vibration of chiral single-walled carbon nanotubes. Budiansky and Sanders (1963) are the source of the stress and strain equations. Both the impact of height-to-diameter ratios and boundary conditions are included in this model. The governing equations are expressed in eigenform using the complex approach. The fundamental frequencies of SWCNTs are obtained by solving this eigenform using MATLAB software. The impact of density and boundary conditions on frequency behavior is examined. For chiral nanotubes, the frequency pattern with two boundary conditions seems to be parallel. As density increased, the frequencies dropped. Frequencies will be higher with a higher index. Compared to the equivalent C-F situation, the C-C frequencies are higher. There is a significant frequency shift between the C-C and C-F boundary condition curves for shorter tubes and shorter chiral indices. This frequency study is anticipated by the author for high frequencies in intriguing electromagnetic devices.
