Waves at interface of dissimilar nonlocal micropolar elastic half-spaces

Abstract

This work is concerned with reflection/transmission phenomena of plane waves at plane discontinuity separating the two distinct nonlocal micropolar solids in perfect contact. Two problems have been investigated by making incidence of (i) a longitudinal displacement wave, (ii) a set of coupled transverse waves. Equations providing amplitude ratios and expressions of energy ratios are presented. Variation of amplitude and energy ratios against incident angle has been studied for particular model. Phase-shift is also depicted for the incidence of a set of coupled transverse waves due to the occurrence of complex valued amplitude ratios. The effect of nonlocality is studied graphically.
