Stoneley waves at an interface between elastic crystals
Abstract
Results recently obtained by Currie (1974) for Rayleigh waves propagating along a tractionfree surface of a semiinfinite anisotropic elastic body are applied to interfacial (Stoneley) waves in an infinite body composed of two anisotropic elastic halfspaces in welded contact. It is first shown how the appropriate secular equation can be constructed directly from complex vectors provided by the analysis of free Rayleigh waves in the constituent halfspaces. It is then proved that the secular equation reduces to a single real relation, thus confirming in full generality that, when Stoneley waves exist, they are not confined to discrete directions of propagation.
