Splet27. nov. 2024 · In fatigue crack growth testing, the measured crack growth rate r diverges toward zero as T is decreased toward T 0.The rate is evaluated as r = dc/dN, where c is the crack length and N is the number of fatigue cycles. The r range where the FCG curve transitions downward, away from the power law slope, F, is from about 10 −7 to 10 −9 … Splet31. avg. 2012 · A minimum threshold stretch of 3.0 is required for crack propagation. The numerical model is able to predict the dynamic crack growth. It appears that the strength and the surface energy vary with the crack speed.
