- 論文の詳細を見る
Accuracy of linear source location of acoustic emission (AE) from weld cold crack of high strength steel is investigated. TGRC test is used which is conceived by the authors to induce the cold crack at an optional position. Specimens of 350 and 2000mm in length are used and two transducers are placed at intervals of 300mm and 1900mm. Main conclusions obtained are as follows: (1) AE source locations are scattered within the crack location±about 10% in the expression of a relative location which is defined to be 0% at one of two transducers and 100% at the other. (2) Arithmeticai mean of AE source location well agrees with the crack location within ±5% of an error at the largest. The standard deviations are about 5%. (3) There is little difference in the accuracy of AE source location between short and long specimens.
