Stochastic Fatigue Life and Reliability Prediction Based on Residual Strength

doi:10.1007/s12204-015-1632-9

Abstract

Abstract: A randomized approach is developed to solve a deterministic equation. The method uses random deterministic approach to achieve the fatigue life based on residual strength and S-N curve. We propose a oneto- one transformation method to deduce the distribution of fatigue life from the residual strength. The proposed method is simple and effective, and can be used for fatigue life prediction. An example is given to illustrate how the method works.
