摘要：

This review is focused on recent progress achieved by mesoscopic simulations of plastic deformation. The methods presently available for discretizing the dislocation lines are critically discussed with emphasis on a new lattice-based model. Progress in large-scale simulations is represented by a study on the influence of long range elastic stresses on the formation of dislocation patterns in fee crystals. A hybrid discrete-continuum method that provides an exact treatment of the boundary conditions is described and illustrated by an investigation of the critical conditions for dislocation motion in the channels of gamma/gamma ' superalloys.
