The fatigue endurance ratio is defined as the ratio of the fatigue limit (Sc) to the tensile strength (Su) for a given set of conditions.
The endurance ratio is consistently in the 0.4-0.5 range, with an average of about 0.45.
In this study, fatigue endurance ratio
([[sigma].sub.e]/[[sigma].sub.u]) is the ratio of fatigue strength at 5 million cycles over the static tensile strength.
No statistically significant differences were observed in deficit and endurance ratios
between the two groups (p>0.05) (Figures 4 and 5).
He stated that the price of such policies is inherently linked to the degree of risk involved in and endurance ratios
of those companies and facilities seeking coverage.
