Notes:
The multi-axial constitutive behavior of poled and unpoled ferroelectric ceramic PZT53is measured under different proportional tension-torsion loading and compression-torsion loadinguntil 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 tomaximal principal normal stress rule. For poled PZT53, the effect of bias electric field on itsmultiaxial behavior has also been exploited.The results indicated that the “Switching” surfacedisappear with the increased bias electric. The ultimate goal is to develop an experimentallyvalidated micromechanics based phenomenological constitutive model for ferroelectric materials
