According to the relevant KTA-Rules, e.g. KTA 3201.2 ( KTA, 1994), strain correction factors— K e-factors—have to be used in the fatigue analysis of pressurised components if the strain intensity ranges are determined by elastic analyses, and if in this case the range of primary plus secondary stres...
