Abstract
The applicability of the proposed methodology to defect detection tests is studied once the TBEM results have been verified by means of known analytical solutions. Heat diffusion generated by a 3D point heat source placed in the vicinity of a crack is modeled. The resulting thermal waves phase is compared with that obtained when the defect is absent, so as to understand the influence of crack characteristics on the IRT data results analysis, especially on the phase-contrast images. Parameters such as the size of the crack, its shape, its position (buried depth and inclination) and its distance from the heat source are analyzed. Some conclusions are drawn on the effects of varying those parameters.
