The present work emphasises the potentialities of dislocation dynamics simulations for performing analyses of crystal plasticity and obtaining information that cannot be reached by experiment. As an example, a study is presented of parameters that are critical for modeling strain hardening in face-centred cubic crystals, the mesoscopic coefficients of interaction between non-coplanar slip systems.
