Probabilistic Low Cycle Fatigue Life Prediction Using an Energy-Based Damage Parameter and Accounting for Model Uncertainty

Abstract: Probabilistic methods have been widely used to account for uncertainty of various sources in predicting fatigue life for components or materials. The Bayesian approach can potentially give more complete estimates by combining test data with technological knowledge available from theoretical analyses and/or previous experimental results, and provides for uncertainty quantification and the ability to update predictions based on new data, which can save time and money. The aim of the present article is to develop… Show more

“…According to the irreversibility and randomness of fatigue damages, fatigue life prediction methods can be classified into two groups: deterministic fatigue life prediction methods and probabilistic fatigue life prediction methods [3,[10][11][12]. In this section, the most commonly used deterministic fatigue life prediction methods are reviewed.…”

“…Since structural integrity of engineering components are directly affected by physical variability, statistical uncertainty, model uncertainty and errors [3]- [5], quantifying and controlling these uncertainties are essential to enhance the competitiveness in designing fatigue critical products such as turbine engines and railway axles [6]- [9]. Moreover, the development and application of probabilistic approaches with Physics-of-Failure (PoF)-based methods is imperative for valid structural integrity assessment of engineering components under complex loadings, i.e.…”

“…Hence, the changes in the physics of the interaction should be taken into account to evaluate the 'third body' characteristics. Since the nature of contact interaction is probabilistic [15][16][17], it is clear that differences in the structure and chemical composition of materials lead to variable responses during sliding. This means that geometry, physical properties, and wear behaviour of this dynamic system are the probability values.…”
