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, ...

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 ...

Abstract: Abstract. This study presents a novel artificial neural network approach for determining material parameters from single spherical indentation test data, addressing the fundamental nonuniqueness problem inherent in ...

Abstract: Offshore structures are exposed to severe operating conditions because energy resource development has recently extended toward deeper seabed and lower temperature regions. Hence, fracture toughness evaluation for very ...

Abstract: This study examined the fatigue strength and fracture toughness of the structural components of membrane type liquefied natural gas carrier (LNGC) insulation systems, such as reinforced polyurethane foam (RPUF, insulation ...

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 ...

Abstract: Structural safety is one of the most important issues associated with liquefied natural gas (LNG) storage systems, such as LNG carriers, LNG Floating Production Storage Offloading (FPSO), and Floating Storage Regasification ...
