Effects of surface–interface theory on the circumferential shear horizontal wave in a piezoelectric composite cylinder

Mechanics of Advanced Materials and Structures, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 22

Published: Feb. 16, 2025

The current work aims to theoretically investigate the surface–interface effects on circumferential antiplane surface wave through a thin piezoelectric (PE) layer cylindrical structure. elasticity has been formulated in coordinate system for PE material. Along with parameters such as and density, charges are also considered. material properties considered heterogeneous make model realistic. dispersion equation shear obtained analytically closed form electrically short open cases using Bessel's function. of essential behavior parameters, coupling parameter radii ratio, heterogeneity parameter, prestress, have illustrated numerical simulation graphs. Each graph displayed lowest two modes facilitate thorough interpretation dispersion. Three-dimensional plots provided interpret field variables. It found that size-dependent sensitive relation only when is thin. study findings could help develop nano/microsized transducers sensors.

Impact of surface/interface elasticity on the propagation of torsional vibration in piezoelectric fiber-reinforced composite and anisotropic medium

Mechanics of Advanced Materials and Structures, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 21

Published: Feb. 29, 2024

This work has explored surface/interface theory-based torsional wave propagation in a piezoelectric fiber-reinforced composite (PFRC) layer on top of functionally graded elastic substrate. PFRC is assumed to be composed fiber and epoxy matrix. Micro-mechanical investigations have been performed determine the coefficients using strength materials (SM) rule mixtures (RM) techniques. The dispersion relation for under nonclassical boundary conditions determined theory. effects surface/interface, volume fractions, heterogeneities phase velocity mode shapes demonstrated graphically.
