KRAK-GAGE®†是一种相对较新的可粘合薄膜换能器，在室温海水(3.5%氯化钠)环境中对HY 80钢进行了腐蚀疲劳裂纹扩展试验。用该方法得到的疲劳裂纹扩展数据与柔度法和常用的光学/目视测量结果是一致的。因此，这种新的仪器系统似乎是腐蚀疲劳裂纹扩展测试的一个有价值的补充。此外，Krak-Gage和柔度法的测试数据采集和分析都是计算机自动化的，这为这种通常劳动密集型的疲劳裂纹扩展实验节省了相当多的成本。此外，FRAC-Tomat/Krak-Gage仪器系统可用于直接控制试验机，从而实现完全自动化的疲劳裂纹扩展试验。
The application of a relatively new, thin-film bondable transducer, commercially available under the name KRAK-GAGE®†, was evaluated for corrosion fatigue crack propagation tests in a sea water (3.5%NaCl) environment at ambient temperature on an HY 80 steel. Fatigue crack growth data generated by this method are shown to be consistent with those obtained by the compliance method and the commonly used optical/visual measurements. Thus, this new instrumentation system appears to be a valuable addition for corrosion fatigue crack growth testing. Furthermore, test data acquisition and analysis of the KRAK-GAGE and the compliance method were computer automated, which results in considerable cost savings for such customarily labor intensive fatigue crack propagation experiments. Additionally, the FRAC-TOMAT/KRAK-GAGE instrumentation system can be utilized for direct test machine control, permitting completely automated fatigue crack growth testing.
