Description

Rayleigh wave based NDE methods have been hampered by the lack of a theory to describe the scattering process. In previous meetings we have discussed numerical schemes which model the two dimensional problem of plane Rayleigh waves scattering from a plane defect [1], and recently we have presented preliminary details of a simple three-dimensional model [2] for plane Rayleigh wave scattering from surface features accommodated on a Cartesian grid of points. In this paper we will present an analysis of plane Rayleigh wave scattering from a three dimensional surface slot and discuss results for plane Rayleigh wave scattering from a semi-circular trench.

Rayleigh Wave Scattering from Three Dimensional Surface Slots and Semi-Circular Depressions

Brunswick, ME

Rayleigh wave based NDE methods have been hampered by the lack of a theory to describe the scattering process. In previous meetings we have discussed numerical schemes which model the two dimensional problem of plane Rayleigh waves scattering from a plane defect [1], and recently we have presented preliminary details of a simple three-dimensional model [2] for plane Rayleigh wave scattering from surface features accommodated on a Cartesian grid of points. In this paper we will present an analysis of plane Rayleigh wave scattering from a three dimensional surface slot and discuss results for plane Rayleigh wave scattering from a semi-circular trench.
