Reflection and Transmission at the Boundary Surface of Thermoelastic Swelling Porous Media

Rajneesh Kumar, Divya Taneja and Kuldeep Kumar

The present investigation is concerned with the propagation of waves and their reflection and transmission from a plane interface between two different swelling porous thermo elastic half-spaces in welded contact. It is shown that there exist two dilatational waves, thermal wave and two transverse waves propagating with different velocities. The amplitude ratios of various reflected and transmitted waves are computed and presented graphically. It is found that amplitude ratios of reflected and transmitted waves are functions of angle of incidence, frequency and swelling porosity of the media. A particular case has also been deduced from the present investigation. The present investigation has immense application in geophysics and manufactured materials.
