Love-Type Waves in a Piezoelectric Layer Clamped Between a Nonlocal Elastic and a Microstructural Media Subjected to Imperfect Contacts

This study investigates the propagation of Love-type waves in a piezoelectric layer and non-local elastic orthotropic layer resting on a microstructural couple-stressed half-space. Analytical solutions to the governing equations yield mechanical displacement and stress components. By applying relevant boundary conditions, dispersion equations for Love-type wave propagation are derived. Special cases are compared to the classical Love-type wave dispersion equation to validate the results. Numerical simulations and graphical illustrations demonstrate the significant influence of nonlocal elasticity, initial stress, piezoelectric constant, dielectric constant, thickness ratio, couple tension, and imperfection parameters on Love-type wave phase velocity, considering perfect and imperfect interfaces under electrically short conditions. This research provides valuable insights for designing efficient piezoelectric devices, sensors, and energy harvesting systems.
