Now, they do specify that 7 hours is the endurance limit for our life form."

The concept of endurance limit was introduced in 1870 by August Wöhler.

"I know the endurance limits of a machine-that can be found mathematically-and this ship's only a machine.

The endurance limit for notched specimens (and thus for many practical design situations) is significantly lower.

He concludes that cyclic stress range is more important than peak stress and introduces the concept of endurance limit.

By contrast, steel and certain other structural metals and alloys do have an estimable fatigue endurance limit.

However, when the stress is kept below "fatigue stress" or "endurance limit stress", the part will endure indefinitely.

These exoskeletons reduce the possibility of the wearer becoming fatigued and reaching their physiological endurance limit during critical military or industrial missions.

"Now, by taking into account the endurance limits of an average male person, we can make an educated guess in respect with the farthest point that he reached.

Fatigue limit and Endurance limit determines the durability of the frame when subjected to cyclical stress from pedaling or ride bumps.

However, recent research suggests that endurance limits do not actually exist, that if enough stress cycles are performed, even the smallest stress will eventually produce fatigue failure.

Despite its high initial strength-to-weight ratio, one structural limitation of CFRP is its lack of a fatigue endurance limit.

ASTM does not define endurance limit, the stress value below which the material will withstand many load cycles, but implies that it is similar to fatigue limit.

The failure in maintaining the motor task defines the endurance limit, and endurance time is the total duration of the task up to the endurance limit.

It has been shown that, in sustained motor tasks, changes at different levels, including motoneural discharge behaviour, develop before an endurance limit is reached, phenomenon called 'central fatigue' [ 7 8 ] .

For some materials, there is a theoretical value for stress amplitude below which the material will not fail for any number of cycles, called a fatigue limit, endurance limit, or fatigue strength.

Fatigue limit, endurance limit, and fatigue strength are all expressions used to describe a property of materials: the amplitude (or range) of cyclic stress that can be applied to the material without causing fatigue failure.

The flexural fatigue tests on corroded panels demonstrated that endurance limit losses were lower for the steels containing molybdenum or titanium (approximately 9,000 lb/in2) than for those containing columbium or no additional alloy element (approx.

A wayang kulit will run at the World Music Hall at Wesleyan University in Middletown from 8 P.M. Friday to about 3 A.M. Saturday - a bit short of all night, but acknowledged to be the endurance limit of Western audiences.
