著者：Md. Tawhidul Islam Khan題名：Acoustic Emission Technique-an influential NDT tool in Damage Clarification and Source Location発表情報：4th International Conference on Informatics, Electronics & Vision (ICIEV)キーワード：AE technique, Non-destructive evaluation, Pearlite Ductile cast iron, Damage source location.概要：抄録：Non-Destructive Testing (NDT) is an interesting and important topic in diagnostics and safety measurements. Acoustic Emission (AE) technique has been presented in the present topic as NDT to clarify the damage characteristics of pearlite ductile cast iron due to having cracks and micro-cracks in it. As pearlite type spheroidal graphite cast iron has high strength as well as excellent workability and damping capacity, it has been widely used as automobile and many other machine parts. However, the damage initiation and propagation of this type of spheroidal graphite cast iron might depend not only on the graphite size but also on the distribution of the graphite nodules. Therefore, the cracks are initiated from the larger or coarser graphite nodules. The failures of pearlite ductile cast iron caused by tensile and fatigue loadings have been investigated sequentially by AE technique as a non-destructive evaluation (NDE) tool. AE events during the initiation of cracks and micro-cracks have been investigated and characterized by analyzing AE parameters. The results are compared by the microstructural analysis as well. Damage source location capability of AE technique improves its potential applications in wide areas of industrial and biomedical fields as well.英語フィールド
