Method of characteristics in electroelastic analysis of a layer subject to dynamic mechanical loading

The paper proposes an analytic procedure based on the method of characteristics to study the nonstationary thickness vibration of a piezoelectric layer polarized across the thickness and subjected to dynamic mechanical loading. The problem is solved for a suddenly applied harmonic mechanical load. The dynamic electroelastic state of the layer is analyzed Translated from Prikladnaya Mekhanika, Vol. 45, No. 1, pp. 82–89, January 2009.
