TRANSMISSION OF WAVE ENERGY THROUGH AN IMPERFECTLY BONDED INTERFACE BETWEEN A LAYER AND A HALF-SPACE OF DISSIMILAR ELASTIC SOLIDS

Wave propagation through an imperfectly bonded interface between a lay er and a half-space of dissimilar elastic solids is considered. Introd ucing the 'jointed' interface as a model of the imperfectly bonded int erface, and treating the three cases of incident P, SV and SH-waves im pinging on the layer, we have obtained reflection and refraction coeff icients of wave energy and have displayed these in graphical forms. A reflected wave of the same mode as the incident wave is the most sensi tive to the strength of the interface for almost the entire range of i ncident angles. Shutting wave energy in the layer is also affected mor e by the stiffness when wavelength is less than the thickness of the l ayer.
