A STUDY ON FATIGUE DAMAGE IDENTIFICATION METHOD OF A BLADE COMPOSITE LAMINATE WITH DELAMINATION DEFECTS (MT)

A STUDY ON FATIGUE DAMAGE IDENTIFICATION METHOD OF A BLADE COMPOSITE LAMINATE WITH DELAMINATION DEFECTS (MT)

Acoustic emission technique can monitor the fatigue damage state of composite materials in real time. The identification accuracy of damage state depends on the processing and extraction of acoustic emission signals. A method of the acoustic emission signal processing based on harmonic wavelet power...
