DEVELOPMENT OF A FREQUENCY-DOMAIN BOUNDARY ELEMENT METHOD FOR 3-D POROELASTODYNAMICS IN GENERAL ANISOTROPY

Abstract

Wave analysis in rocks is widely used in seismology and geophysical exploration. Rocks under the ground have pores and cracks which are saturated with pore fluid. Therefore, in the numerical analysis, consideration of effects of both cracks and pore fluid is required. The aim of this study is development of a frequency-domain boundary element method for 3-D wave scattering in general anisotropic fluid-saturated porous solids. Some numerical results show the validity of our proposed method.
