It was recalled that the dislocation distributions which developed in deformed crystalline materials were usually inhomogeneous; the dislocations formed patterns such as cells, ladders or labyrinths. Although several models had been proposed for the understanding of this self-organized process, it was still unclear which basic phenomena were responsible for the formation of the various structures. The problem was addressed here by means of computer simulation. It was shown that many of the observed features could be reproduced by numerical models.
