Basic Fatigue Analysis - Neil Wimer

Constant life lines are used for finite life fatigue analysis. Long life, or infinite life, is usually defined at 10^6 – 10^8 cycles. When the expected life of the component is less than long life, then a finite fatigue line can be drawn and higher mean and alternating stresses can be applied to the component without a fatigue …

Chapter 9

endurance limit is plotted on the vertical axis together with the ultimate tensile strength on the horizontal axis. In the first quadrant a line is drawn from the endurance limit to the tensile strength. Any combination of alternating stress and mean stress that falls on the lower of the fatigue …
