Stochastic O(N) algorithm for dislocation dynamics

B Bakó and I Groma

Show affiliations


A new computer simulation method based on stochastic integration of the Langevin equations of dislocation motion is proposed for the investigation of the dynamic properties of a system of parallel straight dislocations. The stochastic approach developed for weakly correlated dislocation systems allows for more than dislocations in the simulation area. Relaxation of a system of parallel edge dislocations is presented.
