Using the method of molecular dynamics, the behavior of plastic deformation and defect structure selforganization are investigated in a low-stability condensed FCC-system irradiated with high-energy particles. An analysis of the dynamics of a single edge dislocation and elementary dislocation ensembles, subjected to the action of a post-cascade shock wave, demonstrates that as a result of this action the dislocations are displaced towards the wave source. As this goes on, the roles of both collective effects and external influences on the ensembles of complex interacting defects increase. In particular, the investigation performed in this work demonstrates that the post-cascade shock waves can give rise to migration of not only single edge dislocation but also elementary dislocation ensembles. It is demonstrated that the changes in the dislocation structure of the irradiated material result from the unloading waves following the post-cascade waves, rather than from the latter waves themselves.
