- First-time demonstration of the suitability of pulsed thermography to accurately measure the depth-location of defects within composites. This paper has developed a Nonlinear System Identification (NSI) method to model the temperature decay. This research has given the component defect and below surface degradation assessment a quantitative and accurate technique for the depth measurement and has filled a major research gap. The research contributed to the development of Aerospace Technology Institute’s (ATI) TES Strategy for the aerospace industry sector, a UK-wide initiative to improve manufacturing and health monitoring of critical aircraft components during production and maintenance.
