Estimation of fatigue strength at operational load

The simple way for estimation of fatigue strength at operational load is presented in this paper. It is necessary only to multiply the magnitude of constant amplitude endurance limit of symmetrical stress cycle by three correction factors, taking into account the shape of the spectrum, its asymmetry factor, steady pre-load stress, stress concentration and fatigue life. each of these factors is derived and expressed in the form of analyticl function.

Impact factors; Fatigue life; Stress concentration
