On damping of an edge dislocation vibrations in a dissipative crystal: limiting cases

摘要

The expression for the generalized susceptibility of the dislocation obtained earlier was used. The electronic drag mechanism of dislocations is considered. The study of small dislocation oscillations was limited. The contribution of the attenuation of low-frequency bending dislocation vibrations to the overall coefficient of dynamic dislocation drag in the long-wave and short-wave limits is calculated. The damping of short-wave bending dislocation vibrations caused by an external action of an arbitrary frequency has been investigated. The contribution of long-wave bending dislocation vibrations damping in total drag coefficient at an arbitrary frequency is found.
