Numerical Investigation of Crack Driving Force and Ultimate Bearing Capacity of D1,422 mm X80 Pipelines with Composite Groove Girth Weld

Existing prediction models for the ultimate bearing capacity of circumferential welds are primarily limited to manual or combined automatic welding with single V-grooves, failing to address full-automatic welding with composite grooves, and that is a critical technical gap for la...
