Evaluation of fatigue damage parameters for Ni‐based super alloys Inconel 825 steel notched specimen using stochastic approach

In the present investigation, temperature dependence fatigue strength behavior of Ni‐based Inconel 825 super alloys is investigated. Based on the experimental results, different S–N models have been derived and a suitable model for the prediction of fatigue strength has been proposed. An inverse power as well as exponential relation between the fatigue strength and absolute temperature is demonstrated. The proposed models are used to predict the...
