This theoretical and experimental investigation deals with the electromechanical response of a shockminus;loaded ferroelectric ceramic material. Quartz gauge and voltageminus;mode techniques were used to characterize the mechanical and electrical responses, respectively, of PZT 65/35 to ap;80 kbar. Below ap;20 kbar the wave propagation was dispersive, whereas step shocks were steady between ap;20 kbar and the ap;36minus;kbar Hugoniot elastic limit. Above 36 kbar the final stress states were reached asymptotically and are believed to be steady. The electrical response was complicated by the ferroelectricminus;tominus;paraelectric phase transformation at 60plusmn;3 kbar and the kinetics of the change in polarization. To investigate this latter effect, a kinetic model is developed which gives good agreement with experimentally determined voltage responses.
