涡流检测中缺陷形状可视化的一种新算法

A New Algorithm for Identificating Shape of Crack in Eddy Current Testing

涡流检测反演技术是一种非常重要的反演缺陷形状尺寸的无损检测方法 ,本文运用了 Dirichlet边界条件下涡流检测反演的远场区域导数 ,构造了反演缺陷形状的一种新算法 ,并且给出了算例 ,数值反演的结果与实际缺陷吻合得较好。算法是可行、正确的。

Eddy current inverse technique is very important method to the reconstruct the shape of crack In this paper, using the domain derivative of farfield pattern for eddy current inverse problem with Dirichlet boundary condition, a new algorithm to recover the shape of crack is constructed and some numerical some examples are given, which demonstrate that the algorithm is feasible and correct
