本文研究了涡流检测条件下导电材料中体积裂纹的快速电磁建模。基本的数值方法进行了说明。该模型是在航空制造中使用的铝结构裂纹进行测试。用该方法得到的计算结果显示出令人满意的协议与相应的实验和数值计算结果通过代表裂纹作为非导电表面。
This paper concerns fast electromagnetic modeling of volumetric cracks in conductive materials under eddy-current inspection. The underlying numerical method is described. The model is tested on cracks in aluminum structures employed in aeronautical manufacture. The computational results obtained with the method display satisfactory agreement with the respective experimental and numerical results obtained by representing cracks as nonconductive surfaces.
