“…Also, the effects of a mechanically and electrically imperfect interface on the surface wave phase velocity were obtained . Further, the influence of parameters such as irregularity size, rotation, and initial stress is further exhibited by studying a functionally graded piezoelectric layered structure, which proved that the frequency of the wave can be determined by these parameters. − These key results provide an important reference value for the research of SAW devices. Additionally, in a previous work, we calculated the propagation characteristics of Love-SAW in composite structures of piezoelectric and CPCs, derived dispersion relations, and examined the effects of the viscosity and conductivity of conductive polymer composites on Love-type wave phase velocity and attenuation .…”

Conductive polymer composites (CPCs), characterized by adjustable material parameters and specific responsiveness to external stimuli, exhibit potential utility as waveguide layers on surface acoustic wave (SAW) devices for monitoring applications. In this study, we examine the effect of swelling on the propagation of Love-type waves by subjecting a layered structure composed of a 36°Y-X lithium tantalate (LT) substrate and CPC waveguide layer. Love-type waves are first identified, and the propagation characteristics are analyzed by simulation and experimental comparison on polydimethylsiloxane (PDMS)-based CPC waveguide layers, which are filled with different acetylene carbon black (ACB) mass fractions. The influence of Love-type wave propagation after being subjected to a chemical medium is further explored. The results show that the characteristic frequency shifts of the SAW device are related to the observed swelling response of the ACB/PDMS CPCs. The experimental results are in agreement with simulations, and the frequency shifts with waveguide layer thickness variation are theoretically verified. This study illustrates the use of CPCs as a waveguide layer to modulate the propagation of Love-type waves and explores their application prospects for swelling monitoring.

This paper has done static and vibration response analysis of the sigmoid functionally graded piezoelectric (S-FGP) tapered plate under thermo-electric load with different even/uneven type porosity. The governing equations of plate motion are derived using first-order shear deformation theory (FSDT) based displacement fields with Hamilton’s principle, and material property distribution is considered as per sigmoid law in the thickness direction of the FGP plate. The obtained governing equations are solved using the higher-order finite element method (FEM) with nine noded interpolation functions with 63 degrees of freedom (DOFs) per element. Convergence and the comparison study have been performed to exhibit the efficacy of the present study. It is observed that parameters like the non-dimensional center deflection, non-dimensional stress, and non-dimensional frequency are decreased as the material gradient index increases. The positive and negative types of electric loading have considerable effects on the pre/post type buckling configuration of the porous S-FGP tapered plate under thermal effect. The present analysis results can be used in the various smart structure application made of porous FGP materials.

“…In the area of structures and materials, wave propagation-based tools have found increasing applications, especially in structural health monitoring and active control of vibrations and noise (Achenbach, 1973). Regarding the analysis of traveling plane waves across structures consisting of piezoelectric and FGM elements, there are several studies in the literature (Abad and Rouzegar, 2019; Berezovski et al, 2003; Chaudhary et al, 2017, 2018, 2019; Eskandari and Shodja, 2008; Nirwal et al, 2019; Qian et al, 2008; Sahu et al, 2018; Saroj et al, 2019; Singh et al, 2018; Singhal and Sahu, 2017; Singhal et al, 2018a, 2018b, 2019a, 2019b). As notable examples, Singhal et al (2018a, 2018b) used Wentzel-Kramers-Brillouin (WKB) and Liouville-Green (LG) analytical approaches to study surface waves in piezoelectric composite structures.…”

This paper aims to develop analytical solutions for wave propagation and free vibration of perfect and porous functionally graded (FG) plate structures integrated with piezoelectric layers. The effect of porosities, which occur in FG materials, is rarely reported in the literature of smart FG plates but included in the present modeling. The modified rule of mixture is therefore considered for variation of effective material properties within the FG substrate. Based on a four-variable higher-order theory, the electromechanical model of the system is established through the use of Hamilton’s principle, and Maxwell’s equation. This theory drops the need of any shear correction factor, and results in less governing equations compared to the conventional higher-order theories. Analytical solutions are applied to the obtained equations to extract the results for two investigations: (I) the plane wave propagation of infinite smart plates and (II) the free vibration of smart rectangular plates with different boundary conditions. After verifying the model, extensive numerical results are presented. Numerical results demonstrate that the wave characteristics of the system, including wave frequency and phase velocity along with the natural frequencies of its bounded counterpart, are highly influenced by the plate parameters such as power-law index, porosity, and piezoelectric characteristics.
