...Mohamed Amir Chaker; Ali Triki The branching technique demonstrated an effective ability to attenuate severe hydraulic-head magnitudes into existing steel-pipes-based hydraulic systems. However, there was no detailed exploration of circumferential-stress, radial-strain, and wave-oscillation period...

.... In this paper, a recently proposed stress-based probabilistic model is assessed using fatigue data available for the P355NL1 steel (a pressure vessel steel). The referred probabilistic model is a log-Gumbel regression model, able to predict the probabilistic Wöhler field (P–S–N field), taking into account...

...Cédric Chauvy; Lionel Coudreuse; Patrick Toussaint During fabrication of Pressure Vessels, steels undergo several heat treatments that aim to confer the required properties on the entire equipment, including welds and base metal. Indeed, the production heat treatment of the base material, which...

...Naoki Miura; Naoki Soneda The fracture toughness master curve shows the relationship between the median of fracture toughness and temperature in the ductile–brittle transition temperature region of ferritic steels such as reactor pressure vessel (RPV) steels. The master curve approach specified...

...D. J. Taylor; T. R. Watkins; C. R. Hubbard; M. R. Hill; W. A. Meith Tantalum refractory liners were explosively clad into cylindrical pressure vessels, some of which had been previously autofrettaged. Using explosive cladding, the refractory liner formed a metallurgical bond with the steel...

Fernandes Although intensive research has been carried out to understand the fatigue behavior of steel notched components, under variable amplitude loading, no definite and general robust models have been derived so far...

...Tomasz Tkaczyk; Noel P. O’Dowd; Kamran Nikbin The reel-lay method is a cost efficient alternative to the S-lay and J-lay methods for small to medium size steel offshore pipelines. The quality of the pipeline construction is enhanced by on-shore welding and inspection under controlled conditions...

... becomes more complicated when the welded joint with strength heterogeneity is subjected to dynamic rapid loading; for example, the welded heat-affected zone of pipeline steels is softened and welded underground pipelines are affected by a rapid ground sliding in an earthquake. In this paper...

...Daniel Vasilikis; Spyros A. Karamanos Thin-walled steel cylinders surrounded by an elastic medium, when subjected to uniform external pressure may buckle. In the present paper, using a two-dimensional model with nonlinear finite elements, which accounts for both geometric and material...

...Sotiria Houliara; Spyros A. Karamanos The present paper investigates structural response and buckling of long unstiffened thin-walled cylindrical steel shells, subjected to bending moments, with particular emphasis on stability design. The cylinder response is characterized by cross-sectional...

...Grzegorz Golański This paper presents the results of a research on the influence of regenerative heat treatment on microstructure and properties of a cast steel after long-term operation at the elevated temperature. The material under investigation was G17CrMoV5-10 cast steel taken out (in the form...

...Jie Zhao; Dong-Ming Li; Yuan-Yuan Fang The current paper discusses the selection of Manson–Haferd and Larson–Miller constants on correlation results of creep rupture property in several heat-resistant steels. It indicates that the change in Larson–Miller constant C LM has obvious effect...

...Jie Zhao; Dong-ming Li; Yuan-yuan Fang; Shi-jie Zhu Generally, creep rupture data of a heat-resistant steel can be compressed into a narrow band by using a temperature-time parametric method such as the Larson–Miller or Manson–Haferd method. In order to describe the scattering of the data...
