Stoneley-wave velocities for a solid-solid interface

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.
