Resumen
The present research suggests an exact analytical methodology for investigating the propagation phenomena of shear acoustic waves into a composite structure encompassed of piezoelectric plate, magneto-elastic transversely isotropic (MTI) layer, and heterogeneous viscoelastic strips bedded on an inhomogeneous half-space. To study the problem, the classical dynamical coupled theory has been adopted. The Whittaker special function and analytical methods have been employed to compute the displacement components. On grooving to the supportable boundary conditions, the frequency equations for shear horizontal-wave have been established in the form of determinants for electrically open and short cases. To ensure the validity of the study, the obtained dispersion equations are further reduced to fairly reflect the Love wave equation in classical theory. To demonstrate the phenomenal impact of different parameters, numerical computations and graphical illustrations have been accomplished for both electrical cases. The results suggest that the existence of electrical constants (viz. piezoelectric and dielectric), magnetic field, dissipation factor, heterogeneity parameter, attenuation coefficient, and order of heterogeneity function into the structure has a significant impact on the velocity profile of the wave for electrically open and short conditions. The findings argue that the outcomes of this specific model have beneficial applications in the fabrication and enhancement of piezoelectric transducers and sensors. In addition, the results attained have an immense ability to deal with various commercial and industrial applications in acoustical engineering, geotechnical design, ultrasonic technology, and surface acoustic waves devices.
