Impacts on SH-Waves Regulating Through a FGPM Plate Clamped Between a Temperature Dependent Plate and a Microstructural Coupled Stressed Substrate Subjected to the Perfect and Imperfect Boundary Conditions

The present article investigates horizontally polarized shear wave (SH-wave) into a composite structure comprised of functionally graded piezoelectric material (FGPM) plate clenched between a temperature dependent plate and a microstructural coupled stress half-space subjected to the perfect and imperfect interfaces. A linear temperature variation taken into the uppermost temperature dependent plate, whereas an exponential depth variation considered into the FGPM plate.

To analyse the problem, the classical dynamical coupled theory has been adopted. Analytical methods have been employed to compute the displacement and stress components of the each medium. With appropriate boundary conditions, dispersion equations for SH-wave propagation have been developed for both cases: in the absence and in the presence of imperfection interfaces of the structure for electrically short case.

Impacts of various involved parameters into the both dispersion equations, on the velocity profile of the SH-wave have been observed by numerical examples and graphical demonstrations. The role of temperature ratio, gradient factor, electric constant, couple tension, imperfection parameter, etc. on the propagation behaviour of SH-wave has been extensively investigated in the considered models. For the analysis and design of SAW devices made of piezomagnetic materials, this work may offer theoretical insight. The results of this investigation have an immense ability to deal with material engineering, industrial engineering as well as geophysics and seismology.
