Abstract An approach to modeling a ferroelectric heterostructure with a prestressed coating made of a two-component functional-gradient material is proposed. Various types of PZT-based ceramics with close values of elastic moduli and significant differences in piezoelectric and dielectric parameters are considered as coating materials. The initial stress state (ISS) of the coating is caused by the action of an electric field and uniaxial mechanical tension. By the example of the problem of the propagation of sh-waves, the influence of the initial electrostatic field on the features of the SAW propagation has been investigated for various ratios of the parameters of the coating materials and the nature of the inhomogeneity localization.
Keywords piezoelectric structure, initial stresses, initial electric field strength, functional-gradient piezoelectric material (FGPM), surface acoustic waves (SAW)
