Reection and transmission in swelling porous media

The present investigation is concerned with the reflection and transmission of plane waves at a interface between two swelling porous elastic half-spaces in welded contact. It is found that their exist two longitudinal waves and two transverse waves. The expression for various amplitude ratios due to the incidence of longitudinal wave in solid (PS)/longitudinal wave in fluid (PF)/ transverse wave in solid (SVS)/ transverse wave in fluid (SVF) have been obtained and depicted graphically. It is found the amplitude ratios of reflected and transmitted waves are the functions of angle of incidence and are affected by the swelling porousity of the media. Surface response at the interface have also been obtained. The results so obtained have been compared with (without swelling porous) elastic medium (EL). The present investigation has immense application in structural problems
