In this work we have begun a comparative study of the propagation of sound waves in carbon nanotubes has single wall using nonlocal elasticity for two different materials such as aluminum designated by (AL) and Nickel (Ni ), one based on the theories of beams of Euler-bernoulli and Timoshenko, the constructions are based on these two materials grace to its lightness and hardness it Frequency equations and modal shape functions of Timoshenko beams structures with some typical boundary conditions are also derived from nonlocal elasticity. The research work reveals the significance of the small-scale effect on wave propagation in single-walled CNTs.
