Paper No: IPC2022-86041
... and is also used in fracture mechanics-based tools, such as CorLAS™, for assessing flaws in cylindrical bodies, such as pipelines. There is limited strain hardening data for pipeline steels in available literature. This led to the development of a correlation utilizing the ratio of yield stress to ultimate...
