Technique and Algorithm for Determining a Complete Set of Compatible Piezoceramics Constants

摘要

We describe an unconventional technique and an algorithm for determining a complete matrix of compatible constants of piezoceramics using one initial specimen; the technique and algorithm are analogous to a conventional method of resonance-antiresonance and provide an enhanced accuracy of measurement results. We measure compatible constants of piezoceramics of the PKR-1, TsTSS_t-5 compositions the values of which are compared with the well-known data. The technique can be used in developing new compositions of piezocomposites.
