ASME STP-PT-071 – Stress Intensity Factor Solutions for Internal Cracks in Thick-Walled Cylinder Vessels

This report describes the analysis methods and results for internal surface crack stress intensity Ksolutions in thick-walled cylinders. The 744 cases include a range of geometry ratios and crack sizeratios for internal axial and internal circumferential surface cracks, axial full-width cracks, and 360ocircumferential cracks. These K solutions extend the K factor solutions available in the 2007 API 579-1/ASME FFS-1 Annex C tables. The results are reported as non-dimensional geometry factors that aretabulated in the appendices along with plots of all the result cases.
