ANALYSIS OF REFLECTION AND TRANSMISSION OF AXIALLY-SYMMETRIC WAVES FOR SELF-REINFORCED HALF SPACE OVER A POROELASTIC HALF SPACE

The objective of this paper is to study the reflection and transmission phenomena in axially symmetric waves in two half spaces, in which the lower one is poroelastic half space, and the upper one is self-reinforced half space. Employing Biot's theory of wave propagation, reflection and transmission coefficients of two dilatational waves, and shear wave are computed against angle of incidence. Numerical results are presented graphically for two types of poroelastic solids, namely, for upper half space, self-reinforced material with the longitudinal, shear modulus and reinforcement parameters respectively and for lower half space the sandstone saturated with water is used. From the numerical results, it is clear that the reflection and transmission coefficients are strongly affected as a function of angle of incidence.
