Summary

The dynamics behavior of an assembly of parallel dislocations is investigated at different length scales. In the first part it is shown that a discrete dislocation system is able to reproduce several important feature of plastic deformation. Then a self-consistent field continuum model is derived. Finally a stochastic approach is outlined, which can be considered as an intermediate scale description between the discrete and the continuum models.
