Multiaxial Electromechanical Couple Behavior of Ferroelectric Ceramic PZT53

Abstract:

Article Preview

The multi-axial constitutive behavior of poled and unpoled ferroelectric ceramic PZT53 is measured under different proportional tension-torsion loading and compression-torsion loading until destroy. Deformation is measured using strain gauges. These results are used to map out “Switching” and “destroy” surfaces. The two surfaces are found to be a function of the polarization. Switching surface is similar to Mises and Tresca yield surface. Destroy behavior corresponds to maximal principal normal stress rule. For poled PZT53, the effect of bias electric field on its multiaxial behavior has also been exploited.The results indicated that the “Switching” surface disappear with the increased bias electric. The ultimate goal is to develop an experimentally validated micromechanics based phenomenological constitutive model for ferroelectric materials.
