REFLECTION OF PLANE WAVES FROM A FREE SURFACE OF A POROTHERMOELASTIC SOLID HALF-SPACE

In the present paper, the reflection of plane waves from a free surface of a generalized porothermoelastic solid half-space is studied.. The appropriate solutions in the generalized porothermoelastic solid half-space are obtained which satisfy the required boundary conditions at the free surface of the half-space to obtain the relations between the reflection coefficients of reflected waves for an obliquely incident plane wave. The paper also discusses the energy partitioning during reflection of plane waves. The reflection coefficients and energy ratios are computed for a relevant material data for a certain range of the angle of incidence. The effects of thermal fields are shown graphically on the reflected waves.
