| Abstract: | The fundamental principles of pulse thermal Infrared nondestructive detection was described and, The thermal mathematical model of defects in composite material was established with the help of a finite-difference model, Some simulated results with Matlab was shown. Based on theoretical and simulating results, a experimental has been provided, practice showed that finite-difference thermal-flow modeling techniques are a powerful and versatile tool to predict defect visibility and to choose the optimum thermal-inspection parameters. |
