摘要
Three-dimensional simulation of eddy current testing (ECT) using finite element method (FEM) has been studied over the past three decades and various methods have been developed. In these methods, the ferrite-core probe is meshed together with the sample. Hence, simulation of probe scanning requires re-meshing, which is not only cumbersome but also a major source of computational noise. In this paper, we propose a novel FEM for the simulation of ECT with ferrite-core probe in which the meshes of ferrite core and sample are generated separately and the coil is not meshed. The new method avoids re-meshing for different probe positions and is simple, flexible, accurate, and efficient.
