Current developments and trends in dislocation dynamics

Recent developments and applications of Dislocation Dynamics (DD) methodology are discussed in the context of their relevance to the Dynamics of Metals program at LLNL and parallel efforts elsewhere. The paper begins with a discussion of existing and developing linkages between DD and atomistic simulations (see the companion paper by Moriarty et al. in this issue). We then continue with an overview of the recent methodological developments leading to a discussion of connections between DD simulations and continuum meso-scale modeling and experiment (see the companion article by Becker et al. in this issue). The section finishes with a brief summary of issues that need to be resolved in the near future for the DD approach to deliver on its promise.
