Velocity of moving edge dislocations in a crystalline solid

The results of a previous analysis examining the energy dissipation rate of edge dislocations moving in a crystalline solid have been extended to predict the dependence of dislocation velocity on the applied shear stress. The result is identical in form with a similar, experimentally observed, relation over a range of dislocation velocities from 10^-3 to approximately 10⁴ cm/s. For still higher dislocation velocities it is shown that the phonon field generated by the rapidly moving dislocations can interact with and resonantly excite the internal molecular vibrational modes of many crystalline solids. At these resonances anomalously large energy dissipation rates occur as energy is efficiently coupled out of the moving dislocations, or plastic wave, and transferred to form local concentrations of excited molecules within the solid.
