Abstract

At first, the unidirectional stress fatigue strength has been made the brief description, and the calculation methods about the fatigue stress under two cases also has been introduced, two cases are the symmetrical and asymmetrical cyclic stress fatigue strength. The calculation of fatigue strength is based on the fact that calculating safety factor is equal to or greater than the allowable safety coefficient. Finally, some alloy steel parts are taken as an example to carry on the fatigue strength calculation.
