Quantitative Analysis of Delaminations,igate materials and structures. We also concentrated on defect detection. Once defects have been located, it is interesting to characterize them quantitatively in order to judge their severity. This sixth chapter is dedicated to this study.

Thermal Diffusivity Measurements of Materials,rst of all, in order to predict the behaviour of a given component or solve the “inverse problem”, it is necessary to perform modelling of the actual experiments. Such modelling requires knowledge of thermophysical properties of the inspected materials.

Applications of Infrared Thermography to High Temperatures,pplication for what we have called . TNDE. However, since infrared equipment can be employed in high temperature contexts, it was found interesting to include a short discussion on this subject in this book (for instance both AGEMA model 880 and Inframetrics model 760 radiometers are capable of measurement up to 1500 °C).

Overview of Nondestructive Evaluation (NDE) Using Infrared Thermography,thermodynamics introduces the energy conservation principle and explains that any (industrial) process consuming energy will see a great part of this energy be transformed into heat (following the law of entropy). Temperature is therefore an important parameter to measure. The glass thermometer, inv

Theoretical Aspects, coverage of this matter). Contrary to measurement of time, frequency or voltage, where resolution of the order of 1 part in 10. or even 10. can be obtained, in radiometry a resolution of only a few percent is generally the best that can be envisaged and only in very careful experimental conditions.

Experimental Apparatus,piro and Schlessinger 1989) such as the infrared (IR) camera, the image acquisition and analysis system and the thermal stimulation system (Fig. 3.1). In this chapter, we will focus our attention on the main elements of the thermographic inspection system illustrated in Fig. 3.1.

External Thermal Stimulation: Methods and Image Processing,o a thermal pulse and analysing the temporal temperature response of the workpiece surface in order to discover eventually anomalies linked to subsurface flaws. As reviewed in Chap. 1, the optimum time of observation is proportional to the square of the depth . for the defect considered and the TNDE
