Thick-Wall Cylinder Reference Stress Crack Solutions for API 579-1/ASME FFS-1 Annex 9C

Greg Thorwald, Lucie Parietti
Proc. ASME. PVP2021, Volume 3: Fluid Structure Interaction; High Pressure Technology, V003T05A009, July 13–15, 2021
Publisher: American Society of Mechanical Engineers
Paper No: PVP2021-61075
https://doi.org/10.1115/PVP2021-61075
... Abstract A new set of reference stress solutions for cracks in thick-wall cylinders were computed for addition in the next edition of the API 579-1/ASME FFS-1 standard, and are described in this paper. The geometry cases used ratios for the cylinder radius, wall thickness, crack depth...
