摘要：
We describe the propagation of rotational elastic waves in a cylindrical waveguide with wedge dislocation in the framework of geometric theory of defects. The defect changes the dispersion relation. For positive deficit angles, it increases the phase velocity and decreases the group velocity of the wave.
