The test results revealed that the failure life was governed by crack propagation in both the low-cycle and high-cycle fatigue regions, and the crack propagation paths differed according to the matching and loading conditions. In addition, the fatigue strengths of the joints were compared for ...
The thermal fatigue life of the friction surface and the bolt holes was differently estimated depending on the influence of the stress amplitude. The strain-life relationship was used to predict thermal fatigue life in view of elastic and plastic deformation. The fatigue cycle ratio was also ...

However, at present, the single low cycle fatigue (LCF) or high cycle fatigue (HCF) model is still used for life evaluations, thus a relatively simple analytical process but perhaps the large deviation is obtained in the damage calculations and life evaluations [6], [7], [8], [9], [...
A novel method is proposed for a combined high and low cycle fatigue (CCF) life prediction model based on Miner’s rule, incorporating load interactions and coupled damage effects to evaluate the fatigue life of wind turbine blades under CCF loading. The method refines the CCF damage curve by...
1. Introduction The fatigue life of wind turbine blades is a critical aspect of turbine performance and reliability research. With the advancement of wind turbine technology, fatigue load analysis, particularly under combined high and low cycle fatigue (CCF) conditions, has become a key factor in ...
