Volume 2 - Fatigue Theory Reference Manual
abaqus-docs.mit.eduOne application of the load is called a fatigue cycle. The loading used in the chain tests is constant amplitude loading because each cycle has the same load amplitude. Commonly used load ratios in fatigue testing are R = 0 where the minimum load is zero, and R = -1 where the minimum and maximum loads are equal and opposite and the mean load is ...
Design and Analysis of a Gas Turbine Blade

Another study was done by Dundas (1994) for gas turbine losses and observed that creep, high cycle fatigue (HCF) and turbine blade cooling related failures added 62% of the total damage costs for gas turbines.
