L51832 Line Pipe Resistance to Outside Force

These reports present the results of a project whose objective was the development of a "patch" to the PRCI ductile flaw growth model (DFGM), so that this successful technology could be extended to include mechanical damage. The ultimate goal is a criterion to assess damage severity based solely on field-measurable inputs and nominal information about the pipeline. It is anticipated that such a criterion will lead to cost-effective, timely action to ensure safety and serviceability of high-pressure transmission pipelines, as continuing use of in-line inspection tools makes it increasingly possible to detect mechanical damage.
