Improved maximum likelihood method for P-S-N curve fitting method with small number specimens and application in T-welded joint [PDF]
Scientific Reports, 2023 In fatigue data analysis, fitting accurate P-S-N curve is problematic if only a small number of specimen is available, especially to evaluate the relationship between the stress level and the standard deviation.

Bi-level Hybrid Uncertainty Quantification in Fatigue Analysis: S-N Curve Approach
Fracture and Structural Integrity, 2020 Due to its physical complexity, fatigue phenomenon inherently presents a significant number of uncertain parameters to be predicted. In uncertainty quantification (UQ), research has demonstrated that even a small variation in uncertain input quantities ...

Fatigue life prediction for acid-resistant steel plate under operating loads [PDF]
Bulletin of the Polish Academy of Sciences: Technical Sciences, 2020 The paper evaluates the causes related to the fatigue damage in a conveyor slide plate, exposed to high-frequency cyclic loads. The plate was made of 1.4301 acid-resistant steel. The fractography showed that the plate failure was caused by fatigue crack.

Probabilistic modeling of S–N curves [PDF]
International Journal of Fatigue, 2014 S-N curve is the main tool to analyze and predict fatigue lifetime of a material, component or structure. But, standard models based on mechanic of rupture theory or standard probabilistic models for analyzing S-N curves could not fit S-N curve on the whole range of cycles without microstructure information.
