High-order mixed finite elements for an energy-based model of the polarization process in ferroelectric materials
Astrid S. Pechstein, Martin Meindlhumer, Alexander Humer
An energy-based model of the ferroelectric polarization process is presented in the current contribution. In an energy-based setting, dielectric displacement and strain (or displac…

Variational inequalities for ferroelectric constitutive modeling
Martin Meindlhumer, Astrid Pechstein, Alexander Humer
This paper is concerned with modeling the polarization process in ferroelectric media. We develop a thermodynamically consistent model, based on phenomenological descriptions of fr…
