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