Insight Into

Abstract The displacement caused by a source on an interface between two solid semi-infinite elastic media presents an excellent study in interference between direct, head and interface waves. The solution herein derived provides fresh insight into the nature of pseudo-Stoneley interface waves. As well, the evolution of the head and direct waves is discerned as they move away from the interface. The technique used to solve the problem demonstrates the simplicity of using Sherwood's (1958) method with generalized ray theory. The displacement is simply expressed in a closed form which can be rapidly evaluated and is straightforward to interpret physically.

Abstract Stoneley-wave velocities for a solid-solid interface were calculated for a wide range of elastic parameters. For density ratio ρ1/ρ2 < 1, the ratio of the Stoneley velocity to the shear velocity of the first medium VST/b1 is almost independent of the Poisson ratio σ1. Similarly for ρ1/ρ2 > 1 VST/b1 is almost independent of σ2. Results are given in graphical form: For ρ1/ρ2 < 1 and 0 ≦ σ1 ≦ 0.50, graphs of ρ1/ρ2 vs. VST/b1 are given for σ2 = 0.00, 0.10, 0.20, 0.25, 0.30, 0.35, 0.40, 0.45, 0.48, and 0.50. For ρ1/ρ2 > 0 and 0 ≦ σ2 ≦ 0.50, graphs of ρ1/ρ2 vs. VST/b1 are given for σ1 = 0.00, 0.10, 0.20, 0.25, 0.30, 0.35, 0.40, 0.45, 0.48, and 0.50.
