概要
- 論文の詳細を見る
AE source location technique is applied to restraint cracking test with single bevel groove for 80kg/mm^2 class high strength steel. The AE data are analyzed in relation to time and location of cracking in order to reveal the propagation behavior of the root crack. Consequently relationship between the crack ratio and the characteristics of AE parameters, changes in AE source location and other AE parameters vs. time, and dependence of average cracked area per AE event on the propagation mode of root crack, and so on are presented. Moreover, propagation behavior of the root crack is discussed from a synthetic judgement on the AE parameters obtained.
