This contribution deals with the numerical modelling of polycrystalline ferroelectric materials considering a sequential laminate‐based approach established for tetragonal single‐crystal ferroelectrics. The particular model [1] is considered and extended to predict the material behaviour of poly‐crystal tetragonal ferroelectric ceramics. The derived laminate‐based model is implemented in a finite element environment to simulate the time‐dependent domain evolution and switching response of a bulk polycrystalline ferroelectric ceramic. © 2016 Wiley‐VCH Verlag GmbH & Co.
