Dynamical Effects of Driven Dislocation Glide through Local Pinnings
  We present effects of dislocation inertia on the driven dislocation glide through local immobile pinnings using a stochastic computational model. The global dislocation velocity at a higher stress range is found noticeably dependent on the dislocation inertia, and the temperature sensitivity is observed to be strongly non-Arrhenius. The statistical analysis indicates that the correlation of the local dislocation kinetic energy is extended at a lower temperature, which results in the enhanced depinning rate by the inertia effect.
