摘要：

We have developed an experimental and computational hybrid system which can be applied to the detection of flaws in structural members. The system consists of an infrared thermal video system by which the temperature distribution of the body surface can be measured, and an engineering work station which carries out image processing of the thermograms. We have applied the developed system to the detection of flaws embedded in honeycomb sandwich constructions. Various types of flaws lying between the honeycomb core and the surface sheet have been examined, and the effects of the thickness of the surface sheet and the combination of materials have been studied. We have found that the method is useful to detect flaws in the honeycomb sandwich structures.
