Titel
Nonlinear piezoelectric model based on switching processes and its Finite Element formulation
Abstract
Piezoelectric materials like lead zirconium titanate (PZT) are increasingly used in high power actuator applications. Modeling these actuators has presented a challenge to many researchers for quite some time. We present a homogenized micro-mechanically based model and discuss its efficient numerical solution by applying the Finite Element (FE) method.
