摘要：

R-curves were measured for ferroelectric ceramic lead zirconate titanate (PZT) with two different grain sizes using the surface crack in flexure technique. Larger grain size resulted in a higher plateau value of the R-curve. This was consistent with the larger amount of ferroelastic switching observed from the stress/strain curve.
