Application of Induction Thermography in Edge Crack Detection

摘要: 从试验和仿真计算两方面对感应激励红外热像无损检测及其在裂纹检测中的应用进行研究。首先采用有限元仿真软件COMSOL对感应涡流及其分布进行建模和分析，在此基础上，构建感应激励红外热像检测系统，对实际铁磁性薄板的边缘裂纹进行检测试验，证明了感应激励红外热像方法在裂纹检测中的效果及其优势。

Abstract: The induction thermography uses induction eddy current as the driving source, which allows the user to capture the eddy current distribution in components in order to detect cracks. Through the experiment and simulation it is proved that dinductive thermography has good effect to edge crack detection.
