Abstract

The depolarization behavior of lead zirconate titanate 95/5 and 52/48 has been well characterized under uniaxial strain with strain rates on the order of 10^6/s, and under quasi-static uniaxial stress loading with strain rates on the order of 0.1–100/s. This study examines the depolarization behavior under uniaxial stress at strain rates on the order of 10 to 10^3/s. Specimens were loaded using a split Hopkinson pressure bar. Loading rates from 7.2 to 92.5 MPa/µs were investigated, with a maximum stress of around 900 MPa. The results show significant depolarization rate sensitivity in lead zirconate titanate 52/48, while lead zirconate titanate 95/5 exhibits two responses above and below the stress rate of 50–60 MPa/µs, both with little rate sensitivity.
