Grain size effects on dislocation and twinning mediated plasticity in magnesium
TL;DR: Grain size effects on the competition between dislocation slip and 10 1 ¯ 2 -twinning in magnesium are investigated using discrete dislocation dynamics simulations in this paper, where it is shown that twinning deformation exhibits a strong grain size effect; while dislocation mediated slip in untwinned polycrystals displays a weak one.
Journal ArticleDOI
The role of twinning deformation on the hardening response of polycrystalline magnesium from discrete dislocation dynamics simulations
TL;DR: In this paper, the mechanical response of micro-twinned polycrystalline magnesium was studied through three-dimensional discrete dislocation dynamics (DDD), and a systematic interaction model between dislocations and (1012) tension twin boundaries (TBs) was proposed and introduced into the DDD framework.
Journal ArticleDOI
Strain rate dependency of dislocation plasticity
TL;DR: This work investigates the strain rate and dislocation density dependence of the strength of bulk copper and aluminum single crystals through discrete dislocation dynamics and molecular dynamics simulations and proposes an analytical relationship, which agrees well with current simulations and published experiments.
Journal ArticleDOI
Precipitation hardening effects on extension twinning in magnesium alloys
TL;DR: In this paper, the authors investigated the influence of precipitates on twinning mediated plasticity and the development of corresponding hardening models that account for twin-precipitate interactions using molecular dynamics simulations.
Journal ArticleDOI
Towards resolving the anonymity of Pyramidal slip in magnesium
TL;DR: In this article, the formation and slip characteristics of dislocations on second-order pyramidal planes were investigated through molecular dynamics simulations, and it was shown that the critical c-axis compressive stress for dislocation is almost seven times higher than that for first-order dislocated planes.
