The present study is concerned with the reflection and transmission of thermoelastic pIane waves at an imperfect interface between two generalized thermoelastic solid half-spaces of different elastic and thermal properties. The generalized thermoelastic theory with one relaxation time developed by Lord and Shulman (1967) has been used to study the problem. The expressions for the reflection and transmission coefficients which are the ratios of the amplitudes of reflected and transmitted waves to the amplitude of incident waves are obtained for an imperfect boundary and deduced for normal stiffness, transverse stiffness, thermal contact conduetance, slip and welded boundaries. The amplitude ratios of various reflected and transmitted waves are also deduced at the interface of two semi-infinite media (I) Elastic/Generalized Thermoelastic and (II) Elastic/Elastic. The special case of stress free thermally insulated boundary has also been discussed. It is found that the amplitude ratios of reflected and transmitted waves are affected by the stiffness and thermal properties of the media.
