領域積分方程式を用いた弾性波動場の散乱および逆散乱解析手法の展開

抄録

A method by means of the volume integral equation for forward and inverse scattering analysis of elastic waves is presented in this paper. The volume integral equation is directly solved by FFT and Krylov subspace iteration technique. The shift operator is also introduced to the inverse scattering analysis to regularize the equation. It is found from the numerical results that the present technique for the volume integral equation is successful for both the forward and inverse scattering problem.
