Raleigh waves radiated from a point source at the boundary free from tensions

We consider such solutions of the elastic theory equations that suffer a discontinuity only at the boundary free from tensions (Raleigh waves). We find initial data for the complex intensity of the surface Raleigh waves in the two simple media. The first elastic medium fills in the half-space with Lame parameters and density depending on the depth. The second medium is bounded by a curve determined by natural equation. The parameters of the second medium depend on the arc-length along the curve. Bibl. – 12 titles.
