Abstract

An approximate theory for scattering of elastic wave by general shaped defects has been developed. A defect of arbitrary shape can be represented by a sphere S and a remainder volume R. Using the exact solution for a sphere and treating R as a perturbation, the solution corresponding to the Distorted Wave Born Approximation is obtained. This solution contains non-trivial frequency dependence and phase information. Preliminary comparisons with experiments will be presented.
