Abstract :
Techniques for automatic monitoring of faults in machinery are being considered as a means to safely simplify or dispense with expensive periodic fault inspection procedures. This paper presents results from an ongoing investigation into the feasibility of using acoustic emissions (AEs) for automatic detection of microcrack formation/growth in machine components
