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.
