RISStudy on Microstructure, Stress Corrosion Cracking Crack Propagation Paths, and Mechanical Field at the Tip of the Stationary-Propagating Crack of Pipeline Steel Girth Welded Joint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: During the service life of oil and gas pipelines, welded joints are critical areas that are susceptible to failure or fracture. This study aims to investigate the influence of mechanical heterogeneity on the mechanical ...
Characterization of Mechanical Heterogeneity and Study of the Mechanical Field at the Tip of the Stationary-Growing Crack in Dissimilar Metal Welded Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The mechanical heterogeneity in local areas of dissimilar metal welded joints and the micro-area mechanical state at the crack tip are key factors in determining Environment-Assisted Cracking (EAC). Traditional methods for ...
