TL;DR: In this paper, numerical algorithms for discrete dislocation dynamics simulations are investigated for the purpose of enabling strain hardening simulations of singlecrystals on massively parallel computers, and the authors propose a deterministic algorithm for single-crystal simulations.

TL;DR: In this paper, the authors used large-scale three-dimensional discrete dislocation simulations (DDS) to explicitly model the deformation behavior of micrometer-scale Ni microcrystals in the size range of 0.5-20μm.

TL;DR: It is reported that interactions among three dislocations result in the formation of unusual elements of dislocation network topology, termed ‘multi-junctions’, which are responsible for the strong orientation dependence of strain hardening in body-centred cubic crystals.

TL;DR: In this article, tight-binding molecular dynamics simulations are performed to study self-diffusion, interstitial-vacancy recombination, and formation volumes of point defects in crystalline silicon.

TL;DR: In this article, a mesoscopic simulation of dislocations and plasticity in b.c. crystals at low temperatures is developed and applied to the case of Ta, where the thermally activated nucleation of double kinks is taken as controlling the mobility of screw dislocation.
