... initiation only. To properly assess the effects of the design, fabrication, inspection, and repair strategy for structure degradation due to crack growth, fracture mechanics (FM) models need to be applied. In this paper, alternative S-N and FM formulations of fatigue are investigated. The probabilistic...

... on these pipelines, resulting in localized wrinkles well into the plastic range of the pipe material. Eventually, there is a possibility of a fracture occurring at a wrinkled location under continuous deformation. A recent field fracture and a failed laboratory specimen have been observed within a telescopic wrinkle...

...Hiroyuki Motohashi; Naoto Hagiwara By conducting curved wide plate tensile tests for girth welded joints of X80 line pipe containing a surface notch in the weld metal, the effects of strength matching on fracture performance were evaluated. Parametric studies were also conducted using a finite...

..., and an analytical method is used to estimate the fracture failure probability. The results obtained from the present method are compared with those obtained from direct Monte Carlo simulations. Both are in good agreement. From the studies in this paper, it is concluded that the most dangerous case is that the crack...
