Cumulative Fatigue Damage Under stepwise Tension-Compression Loading
Rock structures are subjected to cyclic tension-compression loading due to a blasting, earthquake, traffic and injection-production in underground storage case. Therefore study the fatigue behavior of rock samples under this type of loading is required. In this study, the accumulated fatigue damage for a Green Onyx rock sample which consisted of only one mineral composition with two-step high-l...
متن کاملProbabilistic analysis of weld cracks in center-cracked tension specimens
This paper describes the development of a probabilistic methodology for fracture-mechanics analysis of weld cracks in a center-cracked tension (CCT) specimen. It involves elastic±plastic analyses to predict J-integral, statistical models of uncertainties in loads and material properties, and standard computational methods of structural reliability theory for probabilistic analysis. Eighty-one d...
متن کاملCumulative damage modeling of solid lubricant coatings that experience wear and interfacial fatigue
bstract Solid lubricating coatings comprise a large segment of tribological materials and under a spherical contact the coating/substrate interface xperiences cyclic shear stress that leads to delamination of the coatings from the substrate and premature failure. The polymeric solid lubricating oating used in this study is an expanded PTFE/epoxy composite. The coatings experience cumulative dam...
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 کاملFatigue Life Analysis of Crane K-Type Welded Joints Based on Non-Linear Cumulative Damage Theory
Engineering fatigue fracture failure is one of the most common phenomena of mechanical and structural failure, statistically representing approximately 50 to 90% of total mechanical damage [1]. Lattice structures have been widely used in crane booms, steel plants, parking garages, offshore platforms and other fields [2] to [4]. In a crane, the lattice boom has better mechanical properties compa...
