Reflection of plane waves from the surface of a piezothermoelastic fiber-reinforced composite half-space

This work focuses on the study of plane wave reflection at the surface of a piezothermoelastic fiber-reinforced composite (PTFRC) half-space. The classical dynamical coupled theory, Lord-Shulman theory and Green-Lindsay theory have been employed to examine the problem. The existence of four types of waves, viz. quasi-P(qP), quasi-SV (qSV), thermal(T-mode) and electroacoustic(EA) waves has been detected in the two-dimensional model of the PTFRC medium. The closed-form expressions of the amplitude ratios of reflected waves have been obtained by using suitable boundary conditions. The impact of thermal parameters has been extensively studied and total normal energy flux at the surface has been derived.
