Description

This paper reports on progress of research to define the detectability of cracks and related structural defects using acoustic emission (AE). This work is in response to increasing code acceptance of AE, such as the recent Department of Transportation exemption [1] allowing the use of AE to qualify railroad tank cars in lieu of hydrostatic testing, and the pending Coast Guard acceptance of AE for qualification of ammonia barges. Each of these standards requires the establishment of a minimum detectable defect size. Because of the irreversible nature of the mechanisms that cause AE, traditional round robin testing is not possible.
