Signal Characteristics of Acoustic Emission from Welded Exhaust Flange for Fatigue Fracture Prediction
- 발행 : 2007.05.10
초록
The purpose of this work is to obtain fundamental data about fatigue crack detection of the welded exhaust flange by using the AE method. The acoustic emission method as a nondestructive evaluation is one of high technical test for realtime monitoring in the dangerous industry fields. Signal analysis of both AE sensor and accelerometer for fatigue crack failure are presented in this paper.
