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.
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.
