The inverse geometric problem applied to the IR-CAT method for the detection of an irregular subsurface cavity

摘要: Publisher Summary Use of infrared scanners (m-scanners) for the nondestructive detection subsurface cavities, as proposed by Hsieh and his co-workers, is a steady-state thermal method. In this chapter, inverse geometric heat conduction problem solved in IR-CAT method to detect an irregular cavity. An scanner used non-intrusively retrieve surface temperature distribution test sample, which encloses The cavity heated using foil heaters, at measured thermocouples. Cauchy conditions are prescribed exposed surface. BEM-based anchored grid pattern locate determine shape Infrared thermography techniques scanners, sample preparation, calibration curve, retrieval discussed.
