Study of Constitutive Behavior of Ferroelectrics via Self-Consistent Modeling and Neutron Diffraction [PDF]
, 2007 The central goal of this study is to develop a reliable self-consistent model to describe the constitutive behavior of polycrystalline ferroelectrics and to predict their lattice strain and texture evolution. Starting with the model developed by Huber et
