A phenomenological dislocation mobility law for bcc metals
Giacomo Po,Yinan Cui,David Rivera,David Cereceda,David Cereceda,Thomas D. Swinburne,Jaime Marian,Nasr M. Ghoniem +7 more
TL;DR: In this article, a generalized dislocation mobility law in body centered cubic (bcc) metals has been developed and demonstrated in discrete Dislocation Dynamics (DD) simulations of plastic flow in tungsten (W) micro pillars.
Journal ArticleDOI
Recent Progress in Discrete Dislocation Dynamics and Its Applications to Micro Plasticity
Giacomo Po,Mamdouh S. Mohamed,Mamdouh S. Mohamed,Tamer Crosby,Can Erel,Anter El-Azab,Nasr M. Ghoniem +6 more
TL;DR: In this paper, the authors present a self-contained review of the discrete dislocation dynamics (DDD) method for the numerical investigation of plasticity in crystals, focusing on recent development and implementation progress.
Journal ArticleDOI
Singularity-free dislocation dynamics with strain gradient elasticity
TL;DR: In this article, the authors consider the non-singular theory of discrete dislocation loops in gradient elasticity of Helmholtz type, with interest in its applications to three dimensional dislocation dynamics (DD) simulations.
Journal ArticleDOI
A non-singular theory of dislocations in anisotropic crystals
TL;DR: In this article, the authors developed a non-singular theory of three-dimensional dislocation loops in a particular version of Mindlin's anisotropic gradient elasticity with up to six length scale parameters.
Journal ArticleDOI
A coupled dislocation dynamics-continuum barrier field model with application to irradiated materials
TL;DR: In this paper, a new computational methodology for 3D discrete Dislocation Dynamics (DDD) in barrier-strengthened materials is developed, which combines the discrete 3D DDD framework with the Finite Element Method (FEM) solution of a continuum field equation for the evolution of dispersed barriers.
