Transmission of Wave Energy through an Imperfectly Bonded Interface between a Layer and a Half-Space of Dissimilar Elastic Solids

抄録

Wave propagation through an imperfectly bonded interface between a layer and a half-space of dissimilar elastic solids is considered. Introducing the `jointed' interface as a model of the imperfectly bonded interface, and treating the three cases of incident P, SV and SH-waves impinging on the layer, we have obtained reflection and refraction coefficients of wave energy and have displayed these in graphical forms. A reflected wave of the same mode as the incident wave is the most sensitive to the strength of the interface for almost the entire range of incident angles. Shutting wave energy in the layer is also affected more by the stiffness when wavelength is less than the thickness of the layer.
