Discrete dislocation dynamics

DDD simulation is a numerical method that reproduces the plastic deformation of crystalline materials in a physically justified way at the scale of several tens of micrometers down to the atomic scale. This method is particularly well adapted to study the mechanical properties of superalloys as the plastic deformation of such materials is located in volumes with submicrometer dimensions. In this chapter, recent progress of the DDD technique and its important results on superalloys single crystals are reviewed.
