Scattering of a plane harmonic SH wave by multiple layered inclusions

• Scattering of a plane harmonic SH wave by multiple layered inclusions is considered.
• Boundary integral equation method is applied to solve the problem.
• The effects of multiple scattering, the geometry, and the impedance contrast on surface motion are investigated.
• The importance of these factors on the surface response is demonstrated.

Scattering of a plane harmonic SH wave by an arbitrary number of layered inclusions in a half-space is investigated by using a direct boundary integral equation method. The inclusions of arbitrary shape and placement are embedded within an elastic half-space. The effects of multiple scattering, the geometry, and the impedance contrast of the materials for layered inclusions and pipes are considered in detail.
