Sažetak
: It is generaly accepted in design community that known Goodman concept of determining the fatigue safety factor cannot be applied for the prestressed components. However, surprisingly, general formula for determining the fatigue safety factor in the presence of static prestress has not yet been offered. In this paper, the unique formula for determining the fatigue strength amplitude and fatigue safety factor for components subjected to constant amplitude (CA) stress cycling process in the presence of static prestress is derived. The simple formula for determining the HCF life of the prestressed components subjected to an arbitrary CA stress cycling process for known S-N curve and mean and amplitude stresses, on the basis of Goodman line in Haigh diagram, is suggested, as well.
