RESUMO

Reflection and transmission phenomena of plane elastic waves at a plane interface between two different nondissipative porous elastic half-spaces saturated by two immiscible fluids are investigated. The theory of porous elastic media saturated by two immiscible fluids developed by Tuncay and Corapcioglu (1997) is employed. The boundary between the two half-spaces is assumed to be sealed so that the fluids are restricted inside the aggregate. Amplitude and energy ratios of various reflected and transmitted waves are found to be the functions of angle of incidence and elastic properties of the half-spaces. These amplitude and energy ratios are computed numerically for a specific model, and their variations are depicted graphically against the angle of incidence. Results of some earlier authors have been reduced as a particular case of the present formulation.
