Abstract: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. Fo… Show more
