The method successively extracts the smaller interruption cycles from a sequence, which models the material memory effect seen with stress-strain hysteresis cycles. [1] This simplification allows the number of cycles until failure of a component to be determined for each rainflow cycle using either Miner's rule to calculate the fatigue damage ...
Wilhelm Bedzheit Albert (24 January 1787 – 4 July 1846) was a German engineer and mining administrator, best remembered as the first person to record observations of metal fatigue. Albert was born in Hanover and showed early talent as a musician before embarking on the study of law in Göttingen in 1803.
Fatigue detection software is intended to reduce fatigue related fatalities and incidents. Several companies are working on a technology for use in industries such as mining, road- and rail haulage and aviation. The technology may soon find wider applications in industries such as health care and education. [citation needed]
BHP Billiton (NYS: BHP) resists sector weakness through the diversity of its extractive operations, particularly in copper mining, but iron-focused miner Vale (NYS: VALE) doesn't have much to ...
Fatigue has traditionally been associated with the failure of metal components which led to the term metal fatigue. In the nineteenth century, the sudden failing of metal railway axles was thought to be caused by the metal crystallising because of the brittle appearance of the fracture surface, but this has since been disproved.

In the context of cryptocurrency mining, a mining pool is the pooling of resources by miners, who share their processing power over a network, to split the reward equally, according to the amount of work they contributed to the probability of finding a block. A "share" is awarded to members of the mining pool who present a valid partial proof ...
Vibration fatigue is a mechanical engineering term describing material fatigue, caused by forced vibration of random nature. An excited structure responds according to its natural-dynamics modes, which results in a dynamic stress load in the material points. [ 1 ]
Flex drivers are contract workers who use their own vehicles to deliver packages, and competition is so intense that some are using apps to cheat.
