Accession number: 20160601888638 Title: Research on high resolution stress corrosion crack detection based on remote field eddy current non-destructive testing Authors: Xiaojie, Xu1; Yueling, Jia2; Zhanbin, Zhang1 Author affiliation: 1Institute of Information and Navigation, Air Force Engineering University, Xian, China 2Institute of Equipment Management and Engineering, Air Force Engineering University, Xian, China Corresponding author: Xiaojie, Xu Source title: Open Mechanical Engineering Journal Abbreviated source title: Open Mech. Eng. J. Volume: 9 Issue: 1 Issue date: May 29, 2015 Publication year: 2015 Pages: 339-345 Language: English E-ISSN: 1874155X Document type: Journal article (JA) Publisher: Bentham Science Publishers B.V., P.O. Box 294, Bussum, 1400 AG, Netherlands Abstract: Although remote field eddy current had achieved successive application in pipes and tubes non-destructive testing, the poor ability and sensitivity to axial crack such as stress corrosion crack prevented its further application. A novel high resolution remote field eddy current detection method which can be suitable for axial crack especially stress corrosion crack detection was proposed and verified by simulation and experiment. First of all, conventional detection ability of remote field eddy current for crack in different directions was researched with detail. Aside from this, applicability of orthogonal magnetic filed in remote field eddy current was analyzed and simulated by finite element method, and appropriate configuration using to generating orthogonal magnetic fields for tubular structure was discussed and verified. Thirdly, design of detection system including key parameters selection and detection coil mode were researched. At last, proposed high resolution detection system were verified experimentally using various type defects, such as parallel axial crack and real stress corrosion crack. From the above research, conclusions were drawn as followed: the detection ability and sensitivity of proposed remote field eddy current detection system could be improved significantly compared with conventional system, especially for axial crack which was not easily to detect, and real stress corrosion crack could be detected and evaluated successively. © Cui et al.; Licensee Bentham Open.
