Miner's law fatigue

Web1 mrt. 1991 · Two basic features of the model are studied here: (a) the fractal (self-similarity under magnification) property of the damage function, which is predicted by the model and (b) how it leads to a “Modified Miner’s Rule” (MMR), where the fatigue response is dependent on the loading order. Web9 mei 2024 · Fatigue has been proven to be a cause of accidents in workplace. There are a number of high profile cases that demonstrate this causal linkage, such as the Exxon Valdez oil spill, and the Three Mile Island and Chernobyl nuclear disasters. Fatigued workers may exhibit decreased cognitive performance.
