Shock-wave depolarization process of polarized ferroceramic elements under the influence of shock wave is considered in both cases, corresponding to transverse and longitudinal loading. On the basis of developed phenomenological theory numerical model was built, allowing calculation of waveform and energy of pulse, formed at the reactive load of ferroceramic element, during the propagation of shock-wave through this element. Variation of ferroceramic material permittivity and leakage losses due to the shock wave propagations are addressed. Influence of active load value on the pulse magnitude and energy is considered.
