Sažetak
The paper presents the mathematical model for simulation the heat conduction process in the object with defects under material surface. The model is based on the control volume numerical method. The simulation vas carried out for defined start and boundary conditions on the model of known geometry and defects undrer the material surface. The defects are in the form of cylinders containing air. They are olaced on different dimensions. The analysis was carried out in time amplitude domain. The results of the termographic measurements taken on the real model having the same characteristic are given too. Using the data obtained from the thermograms and numerical simulation it is possible to define the geometrical characteristic of the defects by means of the inverse procedure.
