A computer simulation is made of the grain boundary behavior in an aluminum sample under conditions of fast shear loading. The calculations are made using a molecular dynamics method and pseudopotential theory. It is observed that under these loading conditions, the grain boundaries may undergo displacement at an anomalously high speed, even exceeding the rate of the applied shear. The atomic mechanisms responsible for this effect are investigated.
