Abstract:
In this study, we emphasize on the reflection of elastic waves through a homogenous micro-stretch thermoelastic medium. Material and elastic properties of the medium are considered to be temperature-dependent. The medium selected is rotating about an axis with some fixed angular frequency. Initially, the governing equations are formulated with the help of generalized thermoelastic theory. Heat conduction through the medium is encountered by the model proposed by Green and Naghdi. Governing equations are decomposed into longitudinal and transverse components with the help of Helmholtz decomposition principle. Harmonic representation of wave is used to find the solution to the problem.
