title = "Effects of blade curvature on fatigue life of nickel-based single crystal structures with film-cooling holes",
abstract = "The curved thin-walled structures of multi film-cooling holes with different curvatures were adopted to simulate film-cooling turbine blades. The low cycle fatigue (LCF) characteristic was studied based on the theory of crystallographic slip damage. Results show that there is obvious stress interference among cooling holes. Two slip bands around the holes were found linear at approximately 45° and 135° to the loading axis. The maximum resolved shear stress reduces with the increase of curvature radius. Meanwhile, the LCF life positively increases with the changing of curvature radius. When curvature radius is less than 13 mm, it makes a remarkable effect on the resolved shear stress and LCF life; however, when the curvature radius exceeds 13 mm, it can be replaced by the plate structure. Furthermore, an exponential curve is found fitting for the relation between the curvature radius and the logarithmic fatigue life.",
