| Outline of Final Research Achievements |
The aim of this study is to develop a boundary element method for 3-D wave analysis in fluid-saturated porous solids. Waves in rocks under the ground have the following properties: anisotropy, dispersion, and dissipation. Since anisotropic fluid-saturated porous solids can treat these properties, development of a method for wave analysis using the solids has been required. In this study, a fundamental solution for 3-D wave problem in anisotropic fluid-saturated porous solids has been derived firstly. Using the fundamental solution, we developed a frequency-domain boundary element method for wave scattering in the porous solids. Subsequently, a boundary element method for dynamic coupled analysis of isotropic elastic and anisotropic fluid-saturated porous solids was developed. The boundary element methods were applied to some examples, and the results showed the validity of the proposed methods.
