The calibration of the Berlincourt is at a fixed frequency using a sample measured at resonance. In the displacement measurement method the sample experiences tension and compression whilst in the Berlincourt method it is always under compression. The boundary conditions for the two experiments … See more The level of the applied AC measuring force can be varied for some systems. The magnitude of the force is not usually important, as long as the stresses introduced into the material mean the piezoelectric is still … See more The frequency range of the Berlincourt type instrument is limited to a range between roughly 10 Hz–1 kHz. The lower frequency limit is … See more In the investigation of the Berlincourt system it was found that there was a time dependent variation in the measurements. In all cases the measured \mathrm{{d}}_{33} … See more Samples are clamped in position by a small pre-load which is usually applied by turning a screw thread on the measuring head.
