Abstract
The theoretical background of a micromechanically and physically based constitutive model is presented. In addition to the nonlinear ferroelectric behaviour, the model considers the mutual nonlinear coupling of thermal and electromechanical fields. Results are presented in terms of an analytical solution for a one-dimensional problem and single domain configurations. (C) 2016 Elsevier Ltd. All rights reserved.
