A Study of the Influence of the Specimen Anistropy on the Thermal Diffusivity by the Laser Flash Method
Jun Aihara and Masahiro Ishihara
Abstract:An analytical study on thermal diffusivity for anisotropic materials using a laser flash method was carried out to clarify the applicability of the method which has been established for an isotropic materials. A measurement error for anisotropic materials caused by the laser pulse intensity distribution was estimated analytically using a finite element calculation code. In this paper the analytical result on the measurement error of the anisotropic materials was presented and the applicability of the laser flash method to the anisotropic material was discussed.
