Abstract: | 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. |
