Method of arresting crack propagation in line pipe characterized by ductile fracture |
| 摘要 |
A method for arresting a propagating crack in a steel line pipe characterized by ductile or mixed mode fracture which involves providing a mass of material on or around the pipe which is sufficient to constrain or reduce the outward acceleration of the pipe walls behind the crack tip after the crack tip has propagated therepast.
