Fully Plastic Strain Based J Estimation Scheme for Circumferential Surface Cracks in Pipes Subjected to Reeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Modern installation techniques for marine pipelines and subsea risers are often based on the reellay method, which introduces significant (plastic) strains on the pipe during reeling and unreeling. The safe assessment of ...
Methodology for Assessment of Surface Defects in Undermatched Pipeline Girth Welds
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The demand for subsea transport of highly corrosive constituents has noticeably increased in recent years. This has driven the requirement for high strength pipelines with enhanced corrosion resistance such as chromium ...
Cyclic Viscoplasticity Testing and Modeling of a Service Aged P91 Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A serviceaged P91 steel was used to perform an experimental program of cyclic mechanical testing in the temperature range of 400 آ°C–600 آ°C, under isothermal conditions, using both sawtooth and dwell (inclusion of ...
