Resum
The aim of this work is to study the nonlinear behaviour of a ceramic through the analysis of the radial mode at resonance and antiresonance frequencies. To obtain the nonlinear characterization from the impedance measurements, a correction of the current and impedance is proposed in order to obtain simple relationships between the motional impedance and the mean stress. The obtained relations are weakly dependent on frequency. This behaviour is also verified at resonance and at antiresonance. W...
