Fatigue Damage of Joint Welds under Variable Amplitude sm570q h steel

7.1 Validity of Miner's rule
The present work is relevant with respect to two basic assumptions made in the fatigue design of welded joints. Firstly, the fatigue strength of welded joints is dependent only on stress range and the effect of mean stress can be ignored.[25,26]This is based on the assumption that high tensile residual stresses, 7.2 Stress interaction - underloading effect
Although stress interaction under VA loading has been well recognised, much of the work in this area has focused on the tensile overloading effect whereby the effective stress intensity factor range, K eff , for the following lower stress ranges is smaller than the applied due to the crack closure effect, resulting in 7.3 Constant amplitude S-N curve used with Miner's rule
A possible reason for (n/N) values below unity is that crack closure is inhibited under some VA loading regardless of the applied stress ratio or mean stress, such that cyclic stresses in such VA loading spectra produce fatigue damage associated with high tensile mean stress CA loading conditions.
