Resonance interaction of an edge-dislocation wall with a traveling sound wave

The dynamics of an infinite edge-dislocation wall and fragments of this wall in their interaction with a monochromatic sound wave with a nonzero wave vector has been investigated taking into account the mass of dislocations. It has been shown that the drift velocities of the wall fragments significantly increase when the sound wave frequency approaches the natural frequencies of small-amplitude vibrations, including zero frequency. For the infinite wall, a similar increase in the drift velocity is observed for low frequencies and for frequencies close to half the maximum frequency of small-amplitude vibrations of the edge-dislocation wall. The resonance increase in the drift velocity at low frequencies of the sound wave can be important for practical applications.
