On the limits of the energetic coupling between field dislocation mechanics and phase field crystal
Aymane Graini, Jorge Viñals, Manas V. Upadhyay
This paper investigates the energetic coupling between Field Dislocation Mechanics (FDM) and the Phase Field Crystal (PFC) model proposed in Phys. Rev. B 102, 064109, 2020. While F…

A finite deformation theory of dislocation thermomechanics
Gabriel Dante Lima-Chaves, Amit Acharya, Manas Vijay Upadhyay
A geometrically nonlinear theory for field dislocation thermomechanics based entirely on measurable state variables is proposed. Instead of starting from an ordering-dependent mult…

Coupling Phase Field Crystal and Field Dislocation Mechanics for a consistent description of dislocation structure and elasticity
Manas Vijay Upadhyay, Jorge Viñals
This work addresses differences in predicted elastic fields created by dislocations either by the Phase Field Crystal (PFC) model, or by static Field Dislocation Mechanics (FDM). T…
