- W4385888081 abstract "The goals of this research program were to: (1) assess the mechanical and fracture properties of spiral-welded pipe, (2) characterize the crack initiation and maximum load carrying capacity, and (3) determine stress magnification factors for helical flaws. Flattened-strap tensile tests, Charpy V-notch (CVN) tests, and JIC fracture toughness tests were performed to meet the first objective. Results showed that tensile properties are independent of specimen orientation, while CVN data varied by as much as 3 to 1 for parallel vs. transverse machined specimens. Full-scale pipe fracture experiments were conducted to meet the second and third objectives. Results showed that crack initiation was parallel to the rolling direction regardless of the principle stress direction. Stress magnification factors were also developed for through-wall and surface cracks under longitudinal and circumferential stresses. These factors allow design engineers to predict the critical bending stress, circumferential stress, and flaw size for spiral-welded pipe." @default.
