Surface Motion of Two Canyons for Incident SH Waves by Hybrid Method

The responses to an incident plane SH wave on or near a surface included two canyons which is embedded in an elastic half-plane are investigated. A hybrid method combines the finite element method with series expansion is applied to solve the scattering problems in this study. A subregion encloses the two canyons with a semi-circular auxiliary boundary can be meshed by the finite element method. By using the transfinite interpolation (TFI) produces excellent grid mesh on the subregion. The hybrid method is successfully herein to solve the scattering problem.
