Endurance Limit in Design against Fluctuating Load Formulas
The Endurance Limit of a material is defined as the stress below which a material can endure an infinite number of repeated load cycles without exhibiting failure. And is denoted by S
e
. Endurance Limit is usually measured using the Newton per Square Millimeter for Stress. Note that the value of Endurance Limit is always positive.

FAQ
What is the Endurance Limit?
The Endurance Limit of a material is defined as the stress below which a material can endure an infinite number of repeated load cycles without exhibiting failure. Endurance Limit is usually measured using the Newton per Square Millimeter for Stress. Note that the value of Endurance Limit is always positive.
Can the Endurance Limit be negative?
No, the Endurance Limit, measured in Stress cannot be negative.
What unit is used to measure Endurance Limit?
Endurance Limit is usually measured using the Newton per Square Millimeter[N/mm²] for Stress. Pascal[N/mm²], Newton per Square Meter[N/mm²], Kilonewton per Square Meter[N/mm²] are the few other units in which Endurance Limit can be measured.
