Application of Weakest Link Probabilistic Framework for Fatigue Notch Factor to Turbine Engine Materials

摘要：

　　This paper is concerned with the extension of a recently developed probabilistic framework based on Weibulls weakest link and extreme-value statistics to aero-engine materials like titanium alloy and nickel-base super alloys using simulation strategies that capture both the essence of notch root stress gradient and the complexity of realistic microstructures.
