摘    要:建立合理的应力腐蚀裂纹模型对于利用电涡流法定量评估裂纹大小起着至关重要的作用。通过对应力腐蚀裂纹的电涡流法检测实验信号与模拟信号的分析,研究了应力腐蚀裂纹的导电性。结果表明,讨论应力腐蚀裂纹的等效电阻比单独讨论等效宽度及等效电导率更有意义。采用应力腐蚀裂纹的分布导电性模型更有利于重建基于电涡流信号的裂纹形貌。

关 键 词:电涡流检测    应力腐蚀裂纹    导电性    无损检测

Abstract:The electric characteristic of stress corrosion crack (SCC) in eddy current testing (ECT) through analyzing experimental and simulated signals was discussed. Inspection of SCC firstly was carried out. In the following simulation SCC was modeled based on the results of destructive testing. The results show that it is more appropriate to focus on equivalent resistance of SCC in the eddy current simulation. Furthermore considering the distribution of conductivity enables the better reconstruction of SCC.
Keywords:eddy current testing  stress corrosion crack  conductive character  nondestructive testing
