THE DISCOVERY of fatigue occurred in the 1800s when several investigators in Europe observed that bridge and railroad components were cracking when subjected to repeated loading. As the century progressed and the use of metals expanded with the increasing use of machines, more and more failures of components subjected to repeated loads were recorded. | o VOLUME 19 FATIGUE AND FRACTURE ASM INTERNATIONAL Publication Information and Contributors Fatigue and Fracture was published in 1996 as Volume 19 of ASM Handbook.
