Evaluation of the elastic field in phase-field crystal simulations
Maik Punke, Vidar Skogvoll, Marco Salvalaglio
The phase-field crystal model (PFC) describes crystal structures at diffusive timescales through a periodic order parameter representing the atomic density. One of its main feature…
Hydrodynamic phase field crystal approach to interfaces, dislocations, and multi-grain networks
Vidar Skogvoll, Marco Salvalaglio, Luiza Angheluta
We derive a phase field crystal model that couples the diffusive evolution of a microscopic structure with the fast dynamics of a macroscopic velocity field, explicitly accounting…
A phase field crystal theory of the kinematics of dislocation lines
Vidar Skogvoll, Luiza Angheluta, Audun Skaugen +2
We introduce a dislocation density tensor and derive its kinematic evolution law from a phase field description of crystal deformations in three dimensions. The phase field crystal…
Stress in ordered systems: Ginzburg-Landau type density field theory
Vidar Skogvoll, Audun Skaugen, Luiza Angheluta
We present a theoretical method for deriving the stress tensor and elastic response of ordered systems within a Ginzburg-Landau type density field theory in the linear regime. This…
Dislocation nucleation in the phase field crystal model
Vidar Skogvoll, Audun Skaugen, Luiza Angheluta +1
We use the phase field crystal model to study nucleation of edge dislocations in two dimensions under an applied stress field. A dislocation dipole nucleates under the applied stre…
