The induced polarization, P[sub 3](C/m²), in piezoelectric lead metaniobate was examined as a function of monotonically increasing uniaxial stress parallel to the poling direction. Comparison to the induced polarization as extrapolated from small oscillating force measurements illustrates, as expected, a nonlinear response at high compressive stress levels. The stress level beyond which nonlinearities occur was determined.
