This article explores the characteristics of Love wave in a piezoelectric layer imperfectly bonded over a heterogeneous fluid-saturated cracked dual porous half-space. The governing equations of the piezoelectric layer are solved analytically to determine mechanical displacement and electrical potential. Dispersion equations have been established using suitable boundary conditions for electrically open and electrically short conditions. In a particular case, the dispersion equation is reduced to the classical Love wave equation, which validates the present mathematical model. The effect of different parameters (like imperfection, dielectric constant, piezoelectric, and inhomogeneity) on phase velocity has been discussed theoretically and graphically, along with a comparative study by considering two piezoelectric materials, namely, PZT-4 and BaTiO3.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
