Calculations of Fatigue Life of Structural Components for Loads from the Low and High Cycle Fatigue

This paper presents the calculation results and experimental tests of fatigue life for chromenickel steel 1.4301 (mark of steel: X5CrNi18-10) in programmable load conditions. A 10- step loading program with sequence of cycles Lo-Hi-Lo was used. Calculations of fatigue were carried out with the use of the following methods: stress based approach, strain based approach and stress-strain based approach. The results of calculations and experimental tests prove that the material cyclic properties and conditions of their determination have an influence on consistency of the results.
