“…However, materials having a large induced polarisation compared to the spontaneous polarisation have a strain predominantly quadratic as a function of the applied ac voltage. 330 Results from this study showed a significantly higher second harmonic response for soda-lime glass compared to PZT, indicating that the voltage-induced strain in soda-lime is predominantly due to an induced polarisation. Combining VPFM and LPFM also distinguished between PZT and the soda-lime glass, since vertical and lateral piezoreponses on polycrystalline PZT have a similar amplitude; in contrast, induced dipoles in the amorphous soda-lime glass align along the applied electric field direction, leading to a very low lateral response.…”

“…Ferroelastic stress-strain hysteresis curves for unpoled PZT 40,45,47,49,55, and 60 specimens at 25, 200, and 400 °C are presented in Figure 3. It is apparent that with increasing temperature there is a corresponding decrease in the coercive stress, maximum strain, and remanent strain in all compositions.…”

“…For fixed boundary conditions this tensor can be expressed and measured through derivative of dielectric stiffness with stresses. 4,5 However, this derivative depends on the constraints at the specimen boundaries. The electrostriction tensor ␥ iklm ͑or Q iklm ͒ can therefore vary from one experimental setup to another.…”
