Abstract
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.
期刊介绍：
Mechanics of Solids publishes articles in the general areas of dynamics of particles and rigid bodies and the mechanics of deformable solids. The journal has a goal of being a comprehensive record of up-to-the-minute research results. The journal coverage is vibration of discrete and continuous systems; stability and optimization of mechanical systems; automatic control theory; dynamics of multiple body systems; elasticity, viscoelasticity and plasticity; mechanics of composite materials; theory of structures and structural stability; wave propagation and impact of solids; fracture mechanics; micromechanics of solids; mechanics of granular and geological materials; structure-fluid interaction; mechanical behavior of materials; gyroscopes and navigation systems; and nanomechanics. Most of the articles in the journal are theoretical and analytical. They present a blend of basic mechanics theory with analysis of contemporary technological problems.
