SUMMARY Interfacial waves are considered propagating along, or incident upon, an interface between two orthotropic elastic materials which presents special mechanical matching conditions, involving elastic slip along the whole of the interface or in localized areas (one isolated interfacial crack or a periodic array of such cracks). The study is made with a view to applications in geophysics and dynamical non‐destructive evaluation techniques. The work highlights those results (Stoneley waves, existence of an additional SH mode with a cut‐off, diffraction pattern of the far field) which will be useful in a qualitative and quantitative characterization of the interface, especially concerning the presence of cracks and the quality of the bond.
