摘要：

A computer simulation model is proposed to investigate the plastic behaviour of single crystals oriented for single slip. The dislocation system consists of parallel edge dislocations. The velocity of a dislocation is proportional to the local shear stress and the generation of new dislocation dipoles is allowed. It is shown by computations on an AMT DAP that by applying a constant shear rate the stress-strain relationship corresponds to stage I of single-crystal plastic deformation, and a long-range undulation appears in the stress field of the dislocation system.
