摘要：

The collective behavior of a system of straight parallel edge dislocations under cyclic plastic deformation is investigated. For describing the dislocation pattern formation two different stochastic approaches are considered and compared. In one of them the discrete dislocation system is described by coupled Langevin equations; in the other one a continuum approach is applied. Typical deformation patterns ("matrix structures") are found by stochastic integration. [S0163-1829(99)08825-6].
