gue strength (also referred to as the endurance limit) is the stress below which failure does not occur. As the applied stress level is decreased, the number of cycles to failure increases. Normally, the fatigue strength increases as the static tensile strength increases. For example, Fig. 14.2 Schematic of R.R. Moore reversed bending fatigue machine. SourceRef 1
