TL;DR: In this article, a 3D mesoscopic model to simulate the collective dynamic behavior of a large number of curved dislocations of finite lengths has been developed for the purpose of analyzing deformation patterns and instabilities, including the formation of dislocation cell structures.

TL;DR: In this article, a hybrid elasto-viscoplastic simulation model was proposed to investigate small-scale plasticity phenomena and related material instabilities at various length scales ranging from the nano-microscale to the mesoscale.

TL;DR: Three-dimensional multiscale simulations of irradiated metals are used to reveal the mechanisms underlying plastic flow localization in defect-free channels and observe dislocation pinning by irradiation-induced clusters of defects, subsequent unpinning as defects are absorbed by the dislocations, and cross-slip of the latter as the stress is increased.

TL;DR: In this paper, a hierarchical multiscale modeling methodology involving two distinct bridges over three different length scales is proposed to predict the work hardening of face centered cubic crystals in the absence of physical experiments.

TL;DR: In this article, a 3D dislocation dynamics (3DD) model is proposed to predict macroscopic properties such as flow stress and hardening, and their dependence on microscopic parameters such as dislocation mobility, dislocation structure, and pinning points.
