Abstract

In current paper, wave propagation at the interface of two isolated exponentially graded couple stress thermoelastic media under initial stress has been discussed. It is observed that there are three waves viz. P, thermal, and SV waves propagating with different speeds. The reflection, refraction and energy coefficients of plane waves are calculated numerically and shown graphically with respect to angle of incidence to examine the effect of initial stress parameters.
