Associate Professor Yanhua Sun, School of Mechanical Science & Engineering (MSE) of HUST, attended the 17th International Symposium on Applied Electromagnetics and Mechanics, (ISEM2015) from 15 to 18 September 2015 in Awaji Island, Kobe, Japan. In the conference, he listened to the plenary lectures made by the famous scholars such as Prof. Harvey Thomas Banks from North Carolina State University, USA and the Dr. Nora M. Dempsey from Institute Neel, CNRS & Universite Grenoble Alpes, Grenoble, France, and also learned to the special reports at parallel sessions. He also made an Poster Report named “Pulsed electric flux leakage (PEFL) techniques for defects detection and characterization”, in which In this paper, pulsed electric flux leakage (PEFL), a new electromagnetic (EM) non-destructive testing (NDT) technique, is introduced. Physical experiments with a prototype capacitive probe were carried out. Effects of through-hole diameter of the stainless specimen, surface-crack depth and sub-surface crack inspection were studied. The proof-of-concept results indicated that the PEFL testing method could be used to detect not only the surface defects but also the sub-surface defects, and of complete feasibility and the potential of great practical value as a supplement of conventional NDT methods.
The ISEM2015 Symposium contains several aspects of electromagnetic nondestructive testing (NDT), such as the new principle of electromagnetic NDT, the methodology of electromagnetic NDT, the applications of electromagnetic NDT and the new technology of electromagnetic NDT. Associate Professor Yanhua Sun said that he has gained a lot from this symposium. For instance, he learned about the newest dynamic research of electromagnetic NDT, and also he thought that the more creative idea we own and the much deeper the scholar discussion is, including the electromagnetic theory, simulation and sensing of electromagnetic NDT.
The visit was supported by the international cooperation promoting program funds of MSE.
