Abstract
In this paper, a method for thermal characterization of anisotropic materials taking into account the coupling between the sample and its holder is presented. The originality of this work is to use temperature measurements made by infrared camera on the edges of the sample and introduce them as boundary conditions to get rid of the presence of the support. Using the principle of superposition and adapted integral transforms, it is then possible by an iterative method to obtain simultaneously the material properties in its different anisotropy directions by a least squares method applied to the spatial harmonics of the temperature field. This method is validated and compared with a classical Fourier-Cosine transform through a simulation before being applied to experimental measurements.
