In-situ and real-time tests on the damage evolution and fracture of thermal barrier coatings under tension: a coupled acoustic emission and digital image correlation method

In-situ and real-time tests on the damage evolution and fracture of thermal barrier coatings under tension: a coupled acoustic emission and digital image correlation method

By using a coupled acoustic emission (AE) and digital image correlation (DIC) technique, the failure behavior of air plasma sprayed thermal barrier coatings (TBCs) was investigated. The in-situ DIC observations show that the characteristics of AE signals, extracted from the fast Fourier transform, a...
