Most of these specifics can be related to the behavior of screw dislocations in bcc metals [1] but this relation so far is mostly anecdotal and materials specific differences can often not be explained. We are therefore undertaking significant efforts of building a rigorous multiscale modeling framework to describe these properties qua ntitatively. This is based on an atomistic level understanding of dislocat ion core structures and energetics. These simulations reveal important det ails about the influence of non-Schmid (nonglide) stresses on the mobility of screw dislocations which can then be implemented to mesoscopic discret e dislocation dynamics (DDD) simulations [2].\nI will report examples wher e DDD simulations help to understand elementary processes of dislocation i nteraction and show applications of DDD simulations to studies of plastici ty in small-scale bcc single crystals. I will end with an outlook on the d evelopment of continuum models based on advanced 3D dislocation density me asures with evolution equations that naturally track dislocation motion [1 ].\n[1] D.
