Abstract A model to describe dislocation patterns based on cellular automaton and molecular dynamics is presented, which takes into account the short—range interaction and long--range interaction between edge dislocations with opposite Burger's vectors on the same glide plane or the different glide planes. This model uses molecular dynamics to deal with long--range interaction, and cellular automaton to describe the short--range interaction. Using the model, the dislocation structures of single crystal Cu are simulated under no external stress and applied cyclic stress.

Key words: cellular automaton molecular dynamics dislocation pattern
