Computer experiments were carried out for edge dislocations in a monocrystal that was subjected to an external cyclic force. The simulation used molecular dynamics concepts in order to model interactions between dislocations, and an annihilation process which occurred when either 1 or 2 planes were activated. The results for a glide plane revealed a clear tendency of the dislocations to form walls with a wavelength that was proportional to the reciprocal of the dislocation density. When 2 slip planes were activated, which implied the activation of a climb process, a cellular pattern was observed which had a wavelength that was proportional to the reciprocal of the square root of the dislocation density.
