... with tensile properties, it is worthwhile to characterize the variation of fatigue life within a particular heat of material. Figure 3 shows a plot of life versus hoop stress caused by internal pressure for samples with S nom = 120 ksi, (S y,act = 136.1 ksi) a diameter of 1.5 in. and a wall thickness...
