Abstract: Based on the linear thermal-elastic theory and classical plate theory, the governing equations for a thin plate with dynamic temperature field are established, in which the non-Fourier effect during heat transfer is considered under the heat flux disturbance with very high frequency. The analytic solutions for quasi-static deflection and dynamic deflection of the plate are obtained using the Nowacki approach and Navier method. Through numerical examples, the influence of non-Fourier effect, flux frequency and thermal inertia on the deformation and thermal moment is discussed.
