Paper Number: ISOPE-I-23-429
... and the fatigue crack location of each weld based on the mesh-insensitive structural stress, and compare with the fatigue results with DNV method. The result shows that the girth-weld fatigue on the sag bend section and the touchdown zone belongs to multi-axial fatigue, while the middle section’ girth-weld...
