... pipe. Results show that an increase in the thickness ratio and a decrease in the weld strength will reduce the strain capacity of girth welded pipes, and the increase in internal pressure will weaken the strain capacity of girth welded pipes. The application of unequal wall thicknesses and low matching...

.... The effects of the variation of geometric parameters and the load applications on the pipes strain capacity were investigated. The influence of longitudinal misalignment between adjacent pipes was also investigated. ductile fracture damage model pipelines strain capacity Proceedings of the ASME...

... of the structure. The models were loaded under displacement-controlled condition to introduce traction and torsion loads seeking to understand the effects of combined loads on the strain capacity of the misaligned welded structure. Surface elliptical cracks having different crack-size ratios were modeled to study...

... Abstract High grade pipelines have been the majority in China since the beginning of this century. Some pipelines in mountainous area and other places experienced the ground movement because of geohazards and the disturb of construction activities. The strain capacity is important to keep...
