RISStrain-Based Failure Assessment Based on a Reference Strain Method for Welded Pipelines
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Engineering critical assessment (ECA) is an evaluation procedure for structures with flaws and has been widely applied for assessing pipeline integrity. The standards for structural integrity assessment, including BS 7910, ...
Fatigue Life Estimation for HFMI-Treated Weldments Considering Weld Toe Magnification Factors
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: High-frequency mechanical impact (HFMI) post-treatment is a proven method to improve the fatigue life of welded structures. The positive effects of HFMI treatment are influenced by the weld toe geometries and residual ...
A Study on the Fracture Toughness Evaluation Considering Material Tensile Characteristic for Cryogenic Steel
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: ISO 12135, a representative standard for the evaluation of fracture toughness, was revised in 2021. In the previous standard published in 2016, only yield strength was reflected for material property in fracture toughness ...
