Hysteresis in Piezoelectric Ceramics

Application ID: 90151

Many piezoelectric materials are ferroelectric. Ferroelectric materials exhibit nonlinear polarization behavior, such as hysteresis and saturation at large applied electric fields. In addition, the polarization and mechanical deformations in such materials can be strongly coupled due to the electrostriction effect. This model uses the Ferroelectroelasticity interface to analyze a simple actuator made of PZT piezoelectric ceramic material, which is subjected to an applied electric field and a mechanical load.

This model example illustrates applications of this type that would nominally be built using the following products:
