Real-time acoustic emission testing based on wavelet transform for the failure process of thermal barrier coatings

The fracture type differentiation, quantification, and source identification are desirable and yet intractable in the acoustic emission (AE) testing of a complex coating system. In this letter, a technique combining wavelet transform and conventional AE parameter analysis was developed to study the...
