摘要: An analytical solution is presented for the atomic displacements in steady motion of a dislocation modified Frenkel‐Kontorova model form treated previously by Atkinson and Cabrera. It found that at critical velocity, here termed breakdown ν B, regular postulated priori breaks down, so not valid velocities ≥ B. Furthermore, B less than corresponding macroscopic sound velocity this model. The results computer‐simulation studies behavior stress levels greater those which cause are also presented.
