Wave propagation at unbonded interface between two elastic half-spaces

Abstract

The question whether a Stoneley mode can exist at an u n b o n d e d interface between two elastic half‐spaces is examined theoretically. Explicit conditions for its existence are derived when the two half‐spaces are incompressible or Poisson solids whose elastic constants and material densities are approximately equal.
