Title: Dynamic shock studies of PZT 95/5 ferroelectric ceramic

Abstract

Using gas gun and velocity interferometric techniques, the shock loading, the shock release, and the pressure-shear response of 95/5 PZT ferroelectric ceramic have been determined up to 4.6 GPa. 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 concentration 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. 32 references, 15 figures, 2 tables.
