摘要：
In this paper, the reflection phenomenon of plane harmonic waves in a functionally graded thermoelastic medium is studied based on the generalized theory of thermoelasticity. The boundary is assumed to be stress free and thermally insulated. For the incidence of quasi-longitudinal (QL) wave or quasi-transverse (QT) type wave, there may exist three types of reflected waves. For each reflected wave, the corresponding slowness vector is resolved to define its phase speed and reflected angle. Further, the effect of the functionally graded factor on the phase speeds, reflected angles as well as the reflection coefficients for the incidence of QL or QT wave were investigated and shown graphically.
