Abstract
Applying thermography in thermal non destructive testing (TNDT) gives the new possibilities in detection and defining of the defects in material. Because the temperature distribution on the material surface reflects the situation of its inside structure (including possible defects) each disturbances of temperature field can be used for estimation of the material homogeneity. Numerical methods enables the simulation of unsteady heat transfer through the material, giving the surface temperature distribution for various defects in material. Therefore they help a lot in TNDT research. The paper presents the results of the research carried out on the specimen having different defects under material surface, by means of both mentioned methods.
