Thermal diffusivity identification by 2nd derivative analysis of transient temperature profile

This paper deals with a new method to identify the thermal diffusivity of isotropic materials. Contrary to the flash method, a continuous and constant heating is applied on the rear surface of the sample. An analytical solution of the 1D transient equation is developed based on Green’s function and gives the temperature profile on the opposite surface at the first moments. Regarding the 2nd derivative of this equation, we found that it reaches a maximum value at a characteristic time
