Proc. ASME. IPC2020, Volume 1: Pipeline and Facilities Integrity, V001T03A010, September 28–30, 2020
Paper No: IPC2020-9389
...Abstract Abstract In order for the pipeline industry to usher in the next-level fracture mechanics engineering analysis, reasonable and prudent fracture toughness characterizations are needed to improve burst pressure predictions and fatigue crack growth analysis of pipelines with planar cracks...

Paper No: IPC2010-31076
.... Some 8-mm DWTT specimens (N10 and N11 steels) were straightened using the wing-back technique and therefore no deformation was applied to the test section. The wing-back technique follows the straightening technique as used for fracture toughness testing of welds [15]. Loading Rate Quasi-static tests...
