WebMar 16, 2024 · Standard Test Method for Measurement of Fatigue Crack Growth Rates Significance and Use 5.1 Fatigue crack growth rate expressed as a function of crack-tip stress-intensity factor range, d a /d N versus Δ K, characterizes a material's resistance to stable crack extension under cyclic loading. Webcommon way to monitor FCGR tests is to use a clip gage mounted in the specimen notch and calculate the crack length using the specimen compliance via the crack mouth opening displacement (CMOD). This method has the advantage of generating data di-rectly during the fatigue test without any stop-and-start process,
