Research on the quantitative analysis of subsurface defects for nondestructive testing by ultrasound lock-in thermography... This paper describes the quantitative analysis of the shape, boundary, and depth of subsurface defects by ultrasound lock-in thermography....
Fracture mechanics analyses of subsurface defects in reinforced carbon-carbon joggles subjected to thermo-mechanical loads... The influence of entrapped pressure on the thermo-mechanical fracture-mechanics response of reinforced carbon-carbon with subsurface defects is studied....
A combined three-dimensional digitisation and subsurface defect detection data using active infrared thermography... In an attempt to overcome such problems, we propose a single system based on active thermography approach using heat point-source stimulation to get the 3D digitization as well as subsurface defect detection....
A study of the multisensor estimation method based on fusion technology for subsurface defect depth... directly using the multisensor detecting feature information for the defect identification, an improved multisensor recognition algorithm based on data-fusion technology for subsurface defect depth evaluation is proposed....
