Non-Locality Effects on the Propagation of Shear Waves in Piezoelectric/Non-local Micropolar Layered Structure

Considering the non-local effects in micropolar elastic material this paper studied the propagation of shear waves in a piezoelectric layered non-local micropolar half space composite structure. The general dispersion equation of shear waves in the coupled structure is obtained analytically in the closed form. In the particular case the result obtained is in accordance with the classical Love wave equation. The effects of key factors like non-locality, characteristic length, piezoelectric and elastic constants on the phase velocity of shear waves have been investigated and results are depicted graphically. The theoretical results obtained shows that the phase velocity of shear wave is significantly affected due the presence of non-locality and size effects on small length scale in micropolar elastic material.
