Popis: In this paper the experimental fatigue lives of specimens made of 10HNAP steel with the lives calculated with the Goodman and Gerber methods of cycle amplitude transformation and the Dang Van criterion for uniaxial loading are compared. Cycles were counted with the rain flow algorithm and damage was accumulated according to the Palmgren-Miner hypothesis. This paper includes comparison of the results for constant amplitude loading with a non-zero mean value and for random loading with zero or non-zero mean values. It has been shown that for 10HNAP steel the algorithm of fatigue life calculations using the Dang Van criterion gives satisfactory results.
