(2018) A confidence map based damage assessment approach using pulsed thermographic inspection. NDT & E International, Volume 93, January 2018, pp. 86-970963-8695https://doi.org/10.1016/j.ndteint.2017.10.001https://dspace.lib.cranfield.ac.uk/handle/1826/12622In the context of non-destructive testing, quantification of uncertainty caused by various factors such as inspection technique, testing environment and the operator is important and challenge. This paper introduces a concept of contour-based confidence map and an application framework for pulsed thermography that offers enhanced flexibility and reliability of inspection. This approach has been successfully applied to detect three flat-bottom holes of diameter 32, 16 and 8 mm drilled onto a 5 mm thick aluminium plate with a high accuracy of damage detection (R > 0.97). Its suitability and effectiveness in assessing impact damage occurring in composites have also been demonstrated.enAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/NDTReliabilityThermographyImpact damage assessment;CompositeA confidence map based damage assessment approach using pulsed thermographic inspectionArticle18648928
