Sažetak
It is demonstrated that, in the presence of static prestress, the fatigue strength amplitude calculated after Goodman's criterion is less than the real one. The mistake insight is on the "safe side" in fatigue design computations, but still wrong. This imperfection had been perceived and the unique, general formula for determining the fatigue safety factor in the presence of static prestress is offered. It is also presented the extremely simple way for determining the HCF life for known S-N curve and mean and amplitude stresses, on the basis of Goodman line in Haigh diagram.
