fatigue stress

Among others, fatigue stress can be modeled with imposed stress in a triaxial machine.

E Manufactured from cast grey iron for high damping capacity and resistance to fatigue stress.

In the presence of fluctuating load, this type of detail will influence the allowable fatigue stress range.

While the fixed counterweight trebuchet was devastatingly effective, it was subject to a great deal of fatigue stress during operation.

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

It was then that the FAA realized that older planes could suffer fatigue stress and needed more frequent inspections.

Offering an extensive product base, Sea Rig hardware caters for both the rigors of cruising, and the high fatigue stress of racing.

Paris' law (also known as the Paris-Erdogan law) relates the stress intensity factor range to sub-critical crack growth under a fatigue stress regime.

Also the steel rotor can be nitrided by a new low temperature process which more than doubles the life again, as well as increasing the resistance to fatigue stresses.

Since metal-based meteors are not subject to these metal fatigue stresses, the scientists want to recover samples before they enter the Earth's atmosphere to discover how the meteors' "outer shell" protects them.

After one of these aircraft crashed due to wing separation in flight as a result of fatigue stress cracking, the entire fleet of C-130A airtankers was permanently grounded in 2004 .

The interval between inspections must be selected with a certain minimum safety, and also must balance the expense of the inspections, the weight penalty of lowering fatigue stresses, and the opportunity costs associated with a structure being out of service for maintenance.

A subsequent independent investigation in 1997 led by Douglas Herlihy, a former NTSB investigator, reexamined the site and the wreckage, and found no evidence of an explosion, but rather found evidence of structural failure due to fatigue stress.
