Over the past few decades, discrete dislocation dynamics, a modeling framework allowing for the simulation of the collective motion and interactions of dislocations in crystalline media, has been the subject of intense development worldwide. In recent years, a series of novel numerical algorithms, chemo-mechanical frameworks, and applications have been proposed. These advances have taken the field closer to enabling predictions of the mechanical response of engineering polycrystals, e.g., textured crystalline aggregates with impurities. Further, interesting pathways have been proposed to bridge discrete dislocation dynamics simulations with harmonic transition state theory, thereby delineating potential routes for performing coarse graining from the viewpoint of thermodynamics. This chapter summarizes some of the important recent contributions in the field of discrete dislocation dynamics.
