摘要：

Nowadays a big challenge in dislocation dynamics is to describe the collective behavior of dislocations formed during plastic deformation. The methods proposed so far can be classified into two categories: continuum models and computer simulations. The aim is to establish the link between the two approaches for a simplified dislocation configuration. The properties of the obtained self-consistent field equations are investigated both numerically and analytically Developments of different dislocation patterns are presented and discussed.
