Mobility of dislocations in Aluminum: Faceting and asymmetry during nanoscale dislocation shear loop expansion
TL;DR: In this article, a hierarchical multiscale approach via atomistic and discrete dislocation dynamics (DDD) simulations was used to study dislocation loop expansion in Al with a hierarchical multi-scale approach.

Disclination-dislocation based model for grain boundary stress field evolution due to slip transmission history and influence on subsequent dislocation transmission
TL;DR: In this article , a model for the evolution of stress fields within grain boundaries that accounts for the effects of coherent dislocation transmission is introduced, and the model is implemented into a discrete dislocation dynamics (DDD) code and simulations are performed to understand the influence of non-equilibrium GB stress fields, conditioned by the slip transmission history, on subsequent dislocations transmission.

Role of equilibrium and non-equilibrium grain boundary stress fields on dislocation transmission
TL;DR: In this article, the influence of intergranular stresses induced by equilibrium and non-equilibrium grain boundaries (GBs) on dislocation transmission via the discrete dislocation dynamics simulation method is investigated.

Virtual diffraction analysis of dislocations and dislocation networks in discrete dislocation dynamics simulations
TL;DR: In this paper, the authors proposed a data-analytics-based method to correlate diffraction peak broadening to dislocation density in relaxed dislocation networks based on the generation of virtual diffraction signatures of dislocated crystals and the development of a surrogate model.

On the co-nucleation of adjoining twin pairs at grain boundaries in hexagonal close-packed materials
Darshan Bamney,Laurent Capolungo +1 more
TL;DR: A continuum defect mechanics model investigates the co-nucleation of adjoining twin pairs at grain boundaries in hexagonal close-packed metals, revealing CN is preferred over single twin nucleation for low misorientation angle GBs, especially in Mg.
