Time correlation of 3rd and 2nd oscillation harmonics for piezo-dielectric plates with LiNbO₃ as well as the acoustic emission (AE) parameters as functions of the strain amplitude have been studied. The threshold increase and a hysteresis have been revealed in dependences of the harmonic intensity t...
