BASIC SOLUTIONS OF THE EQUATIONS OF ELECTROELASTIC SHEAR WAVES PROPAGATION IN A PIEZOCERAMIC HALF-SPACE WITH MULTIFACTOR BOUNDARY HETEROGENEITY

The article presents the results of developing an algorithm for numerical-analytical integration in functional power series of a system of differential equations for amplitude components in representations of characteristics of coupled shear electroelastic waves propagating along an arbitrary direction in the isotropy plane of a transversely isotropic half-space of functionally graded piezoceramics with a multifactorial near-surface heterogeneity of physical and mechanical properties described by double exponential functions. The basic solutions of the system of wave equations are obtained in the form of power series.
