摘要：

Dynamic drag of edge dislocations by prismatic dislocation loops has been studied. It has been shown that the appearance of activation in the vibration spectrum of moving edge dislocations leads to the dry friction effect. Numerical evaluations have shown that this effect on dislocation dynamics can be rather significant at high loop concentrations.
