Generation characteristics of acoustic emission during tensile test of SA508 and SS304 materials
Description
Acoustic emission signal from crack growth and fracture should be characterized for the application of structural integrity monitoring of pressure vessel and pipings. In this study, generation characteristics of acoustic emission signal during tensile test of SS508 and SS304 which compose of primary structure of nuclear power plant are evaluated. There is a great difference of AE characteristics between normal specimens and notched specimens of each SS508 and SS304 material. AE generations were mostly observed in the elastic and crack growing region for SS304 and in the elastic and plastic region for SA508. In contrast with SS304, anomalous lack of AE generation was observed during the crack growing region in SA508. This suggest that characteristics of AE generation be caused by crystal lattices and fracture patterns of each material
