Phase field dislocation dynamics formulation coupled with Fourier based micromechanics solver and its application to grain boundary-dislocation interactions
Brayan Murgas, Avanish Mishra, Nithin Mathew +1
A new phase field dislocation dynamics formulation is presented, which couples micromechanical solvers and the time-dependent Ginzburg-Landau equation. Grain boundary (GB)-dislocat…

The structure and migration of heavily irradiated grain boundaries and dislocations in Ni in the athermal limit
Ian Chesser, Peter M. Derlet, Avanish Mishra +6
The microstructural evolution at and near pre-existing grain boundaries (GBs) and dislocations in materials under high radiation doses is still poorly understood. In this work, we…
