Abstract

An electrical network similar to the Mason model is constructed to conform with the electroelastic properties of thin isotropic piezoelectric ceramics of standard shapes under the condition of short stress pulses in this thickness mode. It will be seen that these pulses travel close to the speed of sound in an unbounded medium and that it is possible to calculate the elastic coefficients by setting the two active faces free. Specifically, both λ and μ, the Lamé constants, may be calculated from one measurement.
