Abstract
Small amplitude bending vibrations of a screw dislocation with arbitrary slip plane in an uniaxial ferroelectric is considered, the dislocation line is along the ferroelectric axis. To solve this problem the system of equations was made up. Fourier transform of the Peach- Koehler forces projection on the dislocation slip plane is obtained and a linear response function of a screw dislocation in a ferroelectric to an external force is found. The estimates of the additive to the dislocation effective mass and effective rigidity, the additional contribution to the damping of the dislocation vibrations are obtained.
