Fatigue life modeling of a single crystal superalloy and its thin plate with a hole at elevated temperature

Many low cycle fatigue (LCF) experiments of a second generation single crystal (SC) nickel-base superalloy and its thin plate with a hole are carried out to investigate the effects of crystallographic orientation and stress concentration on the LCF life. The local strain approach and two kinds of modified anisotropic models we proposed are employed to predict the fatigue lives for the SC superalloy and its thin plate with a hole. The results...
