A phase-field model for ferroelectrics with general kinetics. Part I: Model formulation

Autor: Guin, Laurent, Kochmann, Dennis

When subjected to electro-mechanical loading, ferroelectrics see their polarization evolve through the nucleation and evolution of domains. Existing mesoscale phase-field models for ferroelectrics are typically based on a gradient-descent law for the
