Abstract
We propose a very simple model of lattice dynamics of carbon nanotubes . Using a De Launay model, the atomic force constants and phonon densi ty of states are given as functions of the nanotube radius. Elastic co nstants, a Young modulus, and Poisson ratio are derived from phonon di spersion curves for a homogeneous deformation.
