Dynamic Shock Studies of PZT 95/5 Ferroelectric Ceramic
- Sandia National Lab. (SNL-NM), Albuquerque, NM (United States)
Using gas gun and velocity interferometic techniques, the shock loading, the shock release, and the pressure-shear response of 95/5 PZT ferroelectric ceramic have been determine up to 4.6 GPs. Results of these experiments indicate that the material undergoes a phase transformation at 0.5 GPa under dynamic loading conditions. Experiments over the stress region 0.9 to 2.6 GPa indicate that the material is in a mixed phase, with the concentrations of the FE phase diminishing with increasing stress. The kinetics of pore compaction and crush-up behavior dominate the mechanical material response above 2.6 GPa. Results of pressure-shear experiments in combination with that of release wave experiments suggest that dynamic yielding initiates at 0.5 GPa, the pressure at which FE to AFE phase transformation also begins.
