本文提出了通过有限元模拟进行瞬态磁场映射的 3D 可视化，以表征复杂缺陷。在这项工作中，我们通过绘制磁场分布图来分析脉冲涡流 (PEC) 测试在复杂几何缺陷（例如角槽）的检测和表征方面的应用。该调查是通过时间步进 3D 有限元分析 (FEA) 进行的，并从映射中提取特征以进行角槽表征。结果表明基于磁场分布的可视化和绘图的复杂几何缺陷表征的潜在静态或动态特征。预计模拟和磁场分布将有助于传感器（阵列）设计和复杂几何表征的逆模型。
A 3D visualisation of transient magnetic field mapping via finite element simulation for the characterisation of complex defects is presented in this paper. In this work, we analyse the Pulsed Eddy Current (PEC) testing application on detection and characterisation of complex geometry defects, for example angular slots, through the mapping of magnetic field distribution. The investigation is implemented via timestepping 3D Finite Element Analysis (FEA) with features from the mapping extracted for angular slots characterisation. The results indicate the potential static or dynamic features for complex geometry defect characterisation based on the visualisation and mapping of the magnetic field distribution. It is expected that the simulation and magnetic field distribution will help in sensor (array) design and inverse models for complex geometry characterisation.
