Propagation of waves in micropolar viscoelastic generalized thermoelastic solids having interficial imperfections

Abstract

The boundary conditions at an imperfect interface between two homogeneous, isotropic micropolar viscoelastic generalized thermoelastic half-spaces of different micropolar, thermal and viscous properties are solved for reflection and transmission coefficients. The expressions for the reflection and transmission coefficients which are the ratios of the amplitude of reflected and transmitted waves to the angle of incident wave are obtained for Lord-Shulman (L-S theory) theory of thermoelasticity and deduced for normal force stiffness, transverse force stiffness, transverse couple stiffness, thermal contact conductance and perfect bonding. Viscous and stiffness effects on these amplitude ratios with angle of incidence have been shown graphically. Some special cases have been deduced.
