Resonant interaction of edge dislocations with running acoustic waves

摘要

The interaction of equilibrium clusters of straight edge dislocations with a monochromatic soundwave having a non-zerowavevector is investigated taking into account the dislocation mass. We report on a significant increase in drift velocities of clusters when the sound wave frequency approaches a cluster's eigenfrequency. Of practical importance is the increase in the drift velocity observed for clusters with a non-zero topological charge interacting with small frequency sound waves.
