疲劳裂纹扩展测试系统

Test System for Fatigue Crack Growth

本文介绍一套利用电位法编制的疲劳裂纹扩展测试系统，利用本系统再配置适当的硬件就能自动进行疲劳裂纹扩展的数据采集与数据处理，大大减轻试验者的劳动强度，缩短测试时间，并提高测试结果的精度．

In this paper a set of system for testing fatigue crack growth developed by means of electric potential method is introduced. With this system together with appropriate hardware, data- acquisition and data- processing of fatigue crack growth can be carried out automatically, thus the labour intensity may be reduced, the test time shortened and accuracy of result improved.
