The team recommended that the pipeline be replaced with a new one, fabricated using a improved welding process and inspected regularly using non-destructive evaluation techniques.
The failure occurred suddenly, without warning, and was attributed to a crack that had grown to a critical size. The pipeline was inspected regularly, but the crack was not detected until it was too late. principles of fracture mechanics rj sanford pdf pdf work
The team used the following equation to calculate the stress intensity factor: The team recommended that the pipeline be replaced
The team concluded that the pipeline had failed due to a fatigue crack that had grown to a critical size. The crack had formed in the weld region, which had a lower toughness than the base metal. principles of fracture mechanics rj sanford pdf pdf work
