Propagation of waves at an imperfect boundary between heat conducting micropolar thermoelastic solid and fluid media

Abstract

Purpose -The purpose of this paper is to establish a mathematical model to investigate the propagation of waves at an imperfect boundary between heat conducting micropolar elastic solid and fluid media. Design/methodology/approach -Wave propagation and reflection methods have been applied to solve the problem. The expressions for refiection and transmission coefflcients are obtained. The corresponding derivation for the normal force stiffness, transverse force stiffness, transverse couple stiffness and perfect bonding has also been included. Findings -A computer program is developed and numerical results are computed to obtain the reflection and transmission coefficients of various reflected waves with incident waves. Some special and particular cases are also discussed. Originality/value -In this paper, stiffness effect on these amplitude ratios with the angle of incidence has been observed and depicted graphically.
