Thermoelastic Plane Waves at Imperfectly Bonded Interface of Generalized Thermoelastic Cubic-Crystal Solids

Abstract

Thermoelastic plane wave propagation at an imperfect interface between two generalized thermoelastic cubic crystal solid half-spaces of different elastic and thermal properties with one relaxation time has been studied. The thermoelastic theory with one relaxation time developed by Lord and Shulman [1] has been used to study the problem. The amplitude ratios of different reflected and transmitted waves are obtained for an imperfect boundary and deduced for normal stiffness, transverse stiffness, thermal contact conductance, slip and welded boundaries. The variation of amplitude ratios with angle of emergence has been shown graphically. It is noticed that the amplitude ratios of reflected and transmitted waves are affected by the stiffness and thermal properties of the media.
