Abstract: The surface shear wave propagation is studied in elastic semi-spaces separated by elastic layer with an imperfectly bonded interface between layer and semi-spaces. The dispersion equations are obtained analytically describing the surface wave phase speed. Based on the dispersion equation analysis it is shown that the interface imperfectness sufficiently decreases the phase speed and can increase the number of shear wave modes too.

Keywords: surface waves; shear waves; imperfect contact; slip; dispersion; meta interface; composite; biodegradable polymers; tribo-fatigue methodology; layered elastic structure.
