Calculation of temperature field in a plane subjected to a pulsed heat input in the framework of non-Fourier heat conduction theory is investigated in this paper by using the finite element method. Comparison of temperature distribution predicted by the present model with the classical Fourier theory is carried out, and some discussions are made. The results reveal that a quite large difference between two approaches in the temperature distribution is observed and that a wavy pattern of heat propagation in the plane is detected through the non-Fourier simulation. The reflection of the heat wave at the edge of the plane is also observed in the non-Fourier simulation whereas no such reflection phenomenon appears in the classical Fourier heat conduction simulation.
