| 摘 要： | 对应力腐蚀裂纹进行涡流检测定量重构时,因裂纹区域电导率特性尚不明确,影响了裂纹的定量精度.本文将裂纹考虑成由多个等厚层组成的模型,采用高频涡流检测仪器和高精度涡流检测数值模拟程序对应力腐蚀裂纹区域的电导率特性进行了分层研究.通过计算和实验,初步验证了检测方法的可行性,并给出了应力腐蚀裂纹电导率值初步结果.

| Abstract: | For quantitative reconstruction of stress corrosion crack(SCC),high precision can not be obtained without proper conductivity information in crack region.A model in which the SCC was made up of several layers with same depth was set up,and the author studied the conductivity property of each SCC region respectively using high frequency eddy current testing(ECT) system and a high accuracy numerical simulation code of ECT problem.Based on several primary results of experiments and calculations,the validity of... |
