Dislocation-grain boundary interaction-based discrete dislocation dynamics modeling and its application to bicrystals with different misorientations

Xu Zhang et al.

Summary: This article investigates a generalized dislocation-GB interaction model and its application in nanopillars and bicrystals within a three-dimensional multiscale discrete dislocation dynamics framework. It is found that the mechanical responses of bicrystals are influenced by the GB structures and complex dislocation interactions. Furthermore, the specific events of dislocation absorption and emission, as well as the evolution of resolved shear stress and dislocation density, are found to be independent of GB misorientation angles or GB strength.

On the origin of the Hall?Petch law: A 3D-dislocation dynamics simulation investigation

Maoyuan Jiang et al.

Summary: The study revealed that the back stress and associated strain hardening are independent of grain size at low strain, while the grain size effect is controlled by increasing the critical resolved shear stress (CRSS) when decreasing grain size. The evolution of the CRSS amplitude is controlled by two competing strengthening mechanisms, justifying the generic 1/d dependent form of the Hall-Petch law observed in simulations and experiments.
