Response of ferroelectric ceramics to uniaxial stress. [Nb doped PZT 95/5]
Conference

OSTI ID:6170246
Changes in electrical polarization of ferroelectric ceramics subjected to non-hydrostatic stress can be caused by rotation of ferroelectric domains, or, in the case of materials near ferroelectric to antiferroelectric phase boundaries, by a stress-induced phase transformation. Both processes have been observed in mechanical measurements on PZT 95/5. The results may have important implications for the operation of shock-actuated ferroelectric power supplies.
