On Fatigue Life Calculation in Thick-Walled Cylinders with Complex Residual Stresses

Source

The large variation in stress intensity factors corresponding to various material models for a single, radial, straight-fronted crack in a pressurized, partially autofrettaged cylinder leads to a drastic difference in the fatigue life calculations. None of the calculated lives agree with the experimental results. Possible explanations of the discrepancy are given and corresponding correction factors are introduced. The calculated lives based on the corrected stress intensity factor ranges are reasonably close to a set of well-documented experimental results arrived at by Throop and Fujczak.
