The elastic properties of three types of tubular nanostructures, carbon, boron nitride and silicon carbide nanotubes, are studied and compared based on the atomic-scale finite element method. Tersoff-Brenner potential is used to describe the interaction between atoms, and the computational method is established in an atomic-scale scheme similar to the classical finite element method. The Young's modulus is evaluated for these nanotubes, and their buckling behavior are analyzed. It is shown that these nanotubes have similar elastic properties, that is that, the diameter has an obvious influence on the Young's modulus, and the buckling is little related to the length of the nanotubes.
