揺らぎを持つ半無限弾性波動場における領域積分方程式を用いた逆散乱解析手法の展開

抄録

A method for the inverse scattering analysis is presented by means of the volume integral equation. The wave field dealt here is an elastic half space having fluctuations for Lamé constants. The fluctuation of Lamé constants are extracted from the volume integral equation, which is to be solved by FFT and Krylov subspace iterative technique. Several numerical calculations are carried out to verify the present method. It is found from the numerical results that the present method is almost successful to determine the fluctuation of the Lame constants from the scattered wave field.
