Fatigue life prediction at combined HCF/LCF loadingG
For the combined HCF/LCF loading, which stress history is simplified in the way that it consists of one LCF stress block with number of cycles equal to the number of start-up in-service operations and one HCF stress block with summed-up all HCF cycles, the closed form expressions are derived for estimating both the crack initiation life and the crack propagation life at combined HCF/LCF loading. As an example of the use, Smith and Haigh diagrams are obtained for the components made of titanium alloy Ti-6Al-4V, which enable the fatigue limit estimation for designed fatigue life, known load ratio and certain number of HCF cycles per one combined stress block.
