Abstract
This research effort was aimed at developing a state-of-the-art fracture model for pipelines with longitudinal seam weld cracks. Approximately 200 finite element simulations were performed, and the results were fit to a parametric equation. The report contains the theoretical framework of the model, a description of the finite element study, and a set of tables that contain fitting constants for the model. The benefit of this research is the creation of a significantly more accurate model to predict burst pressure of pipes with longitudinal seam weld flaws. Increased accuracy in predictions will improve the integrity of seam welded pipe.
