摘要

在这项研究中，我们开发了一种在涡流测试（ECT）过程中通过使用旋转定向滤波器（RDF）控制电磁场来识别碳纤维增强热塑性塑料（CFRTP）裂纹取向的方法。有限元分析表明，通过应用 RDF 并使其旋转，可以改变并控制 CFRTP 中感应的涡流在任何平面方向上的方向。模拟裂缝的狭缝用于确定 CFRTP 中的裂缝方向。当 RDF 角度与裂纹方向一致时，ECT 输出变化达到最大值。所提出的方法可以识别 CFRTP 中的裂纹走向。

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.
