- Summary:
- Das elektromechanische Verhalten zweier neu entwickelten, auf Natrium-Bismut-Titanat basierenden bleifreier Ferroelektrika sowie daraus bestehenden Zweilagenkompositen wird durch Experimente und numerische Simulationen untersucht. Für die Finite-Elemente-Methode wird hierzu ein dreidimensionales, vollständig elektromechanisch gekoppeltes Materialmodell entwickelt. An Hand einer Parameterstudie werden die elektromechanischen Kopplungseigenschaften der Zweilagenkomposite optimiert. - The electromechanical behavior of two new sodium bismuth titanate based lead-free ferroelectric materials as well as bilayer composites are investigated in experiments and numerical simulations. For the Finite-Element-Method, a fully coupled, three dimensional ferroelectric constitutive model is developed. In a parameter study, the electromechanical coupling of bilayer composite is optimized.
