Abstract
ABSTRACT
This paper presents results of the use of AE signatures to detect the on-set and
propagation of cracks associated with a thrust bearing race. To facilitate the
investigation a special purpose built test-rig was employed which allowed for
accelerated crack initiation on a bearing race. It is concluded that sub-surface
initiation and crack propagation is detectable with AE technology. The results
revealed that selecting the AE technique can significantly improve defect
identification in comparison to conventional methods of analysis.
