Investigation of faceted void morphologies in UO2 by phase field modelling
In the present study a phase field model for high surface energy anisotropy is developed to model the morphologies of voids in UO2. In order to precisely account for the high anisotropy, an alternative forward-backward strategy based on a staggered grid with an averaged interface normal scheme is used in the numerical procedure. A variety of equilibrium void shapes are reproduced with respect to a
