OSTI ID:6416015
An overview is presented of ten tests of 15.2-cm-thick steel pressure vessels containing surface cracks. Flaws in the vessels ranged from 31 to 135 mm in depth, and test temperatures ranged from 0 to 91/sup 0/C. A detailed description of the acoustic emission (AE) monitoring of the most recently completed vessel test, V-7B, and the fatigue crack sharpening of the flaw for test vessel V-8 is also presented. Results obtained during these tests indicate that AE is capable of locating flaws, detecting the onset of flaw growth, and providing an indication of the rate of crack extenstion (immediacy of fracture).
