In-Situ Thermography Investigation of Crack Growth in Armco Iron under Gigacycle Fatigue Loading

In-Situ Thermography Investigation of Crack Growth in Armco Iron under Gigacycle Fatigue Loading

A non-destructive thermographic methodology based on the temperature field is utilized to determine the crack tip position during the very high cycle fatigue (VHCF) test of pure iron and deduce the corresponding fatigue crack growth rate (FCGR). To this end, a piezoelectric fatigue machine is employ...
