Detecting and Monitoring Cracks in Aerospace Materials Using Post-Processing of TSA and AE Data

Thermoelastic stress analysis (TSA) is a non-contact technique for measuring the distribution of stress in the surface of a component subject to cyclic loading by using a sensitive infrared camera. The stress concentrations indicative of a crack can be located and tracked using an optical flow metho...
