Damage Characterization of a Cross-Ply SiC/CAS-II Ceramic Composite Under Fatigue Loading Using a Real-Time Acousto-Ultrasonic NDE Technique

CODEN: JCTRER

Abstract

The application of a real-time acousto-ultrasonic (AU) nondestructive evaluation (NDE) technique to monitor damage during fatigue without stopping the test is presented in this paper. Real-time AU parameters were used to decipher the true nature of damage mechanisms occurring during cyclic loading of a SiC/CAS-II cross-ply ceramic composite. The results of AU were complemented by other NDE techniques. The S-N curve for a SiC/CAS-II cross-ply ceramic composite at room temperature was generated and a study of the failure process during cyclic loading was performed.
