متن کاملCumulative Damage in Fatigue with Particular Reference to the Effects of Residual Stresses by
In this Report factors affecting the accuracy of Miner's Rule are dls-cussed. An nvestlgation 1s also described of the cumulative damage behaviour of DID 5014 alumlnlun alloy lug specuwns using random loading. It 1s concluded that the devlatlons from Miner's Rule observed in the uxestlgation can be ascribed manly to the actlon of residual stresses associated with yielding at tllf point of fatzg...
متن کاملI. Residual Stresses and Their Measurement
Residual (locked-in) stresses in a structural material or component are those stresses that exist in the object without (and usually prior to) the application of any service or other external loads. Manufacturing processes are the most common causes of residual stress. Virtually all manufacturing and fabricating processes — casting, welding, machining, molding, heat treatment, etc. — introduce ...
متن کاملHydrogen Assisted Cracking in Pearlitic Steel Rods: The Role of Residual Stresses Generated by Fatigue Precracking
Stress corrosion cracking (SCC) of metals is an issue of major concern in engineering since this phenomenon causes many catastrophic failures of structural components in aggressive environments. SCC is even more harmful under cathodic conditions promoting the phenomenon known as hydrogen assisted cracking (HAC), hydrogen assisted fracture (HAF) or hydrogen embrittlement (HE). A common way to as...
