Identification of crack orientation in electrically conductive materials using eddy current testing powered by rotational directive filter
In this study, we developed a method to identify crack orientation in carbon fiber reinforced thermoplastic (CFRTP) by controlling its electromagnetic field using a rotational directive filter (RDF) during eddy current testing (ECT). Finite element analysis showed that by applying an RDF and rotating it, the eddy currents induced in the CFRTP can be changed and controlled in any in-plane direction. A slit simulating a crack was used to identify crack orientation in CFRTP. The ECT output change reached the maximum when the RDF angle coincided with the crack orientation. The proposed method can identify crack orientation in CFRTP.
期刊介绍：
NDT&E international publishes peer-reviewed results of original research and development in all categories of the fields of nondestructive testing and evaluation including ultrasonics, electromagnetics, radiography, optical and thermal methods. In addition to traditional NDE topics, the emerging technology area of inspection of civil structures and materials is also emphasized. The journal publishes original papers on research and development of new inspection techniques and methods, as well as on novel and innovative applications of established methods. Papers on NDE sensors and their applications both for inspection and process control, as well as papers describing novel NDE systems for structural health monitoring and their performance in industrial settings are also considered. Other regular features include international news, new equipment and a calendar of forthcoming worldwide meetings. This journal is listed in Current Contents.
