Making use of the continuum model, the phonon density of states (PDOS) are calculated analytically for singlewalled carbon nanotubes (SWNT). Neglecting the interaction between twisting and longitudinal stress, the phonon dispersion relations are also determined analytically. The frequency of the bre
