Özet
In this work, the propagation of planar waves in a homogeneous micropolar thermoelastic medium is studied while the entire body rotates with a uniform angular speed. The coordinate system of the rotating medium is assumed to be stationary, and therefore the kinematic equations have two additional terms, na mely, the gravitational and the Coriolis accelerations. The problem is addressed based on the two-tempera ture thermoelastic model with higher-order time derivatives and dual-phase lag, which can explain the effect
of microscopic features in nonsimple materials. With certain boundary conditions and the normal mode approach, the variations in temperature, displacement, microrotation, and thermal stresses induced by heating
are derived. In the absence of rotation and two-temperature factor, comparison is made with the results of
classical thermoelastic models.
