Uniaxial electromechanical behavior of ferroelectric ceramic PZT-53

Effect of compressive pre-stress and biased electrical field on the uniaxial electromechanical behavior of a soft ferroelectric ceramic PZT-53 is investigated. The emphasis is on the effect of electric and mechanical loading history upon the response of PZT-53 to external loading and on the effect of pre-stress and biased electrical field upon the electro-mechanical coupling behavior. It is found that the uniaxial behavior of the PZT-53 is sensitive to the compressive pre-stress and biased electrical field, and is less sensitive to the loading history. Obtained results are expected to shed insightful light on developing reliable constitutive model for ferroelectric ceramics. C 2006 Springer Science + Business Media, Inc.
