Temperature effects and strain rate effects on the piezoelectric charge production of PZT 95/5

ORAL

Abstract

The effects of varying strain rates and temperatures on the charge output and fracture of the piezoceramic PZT 95/5 have been investigated. The samples are studied in the temperature range of $-20\,^{\circ}\mathrm{C}$ to $+80\,^{\circ}\mathrm{C}$; a range of strain rates (10$^{-4}$ s$^{-1}$ to 10$^{+3}$ s$^{-1}$) is achieved using quasi-static loading equipment, drop weights and Split Hopkinson Pressure Bars. Stress-strain data is obtained, along with high-speed images, allowing the physical processes e.g. fracture, to be quantified.
