This article discusses the vibrational properties of silicon carbide nanotubes with various dimensions, chiralities and boundary conditions. The molecular mechanics-based finite element method is applied to study the mode shapes and natural frequencies of the silicon carbide nanotubes. The results reveal that the natural frequencies of the nanotubes increase with decreasing length, but they do not show monotone behaviors vs. diameter changes. The reasons are discussed in detail.
