Traditional rainflow counting methods require exhaustive traversal of load histories, making them computationally expensive for real-time applications. To address this issue, this present study leverages the increasing demand for efficient high-cycle fatigue (HCF) life estimation methods, combining neural network surrogate modeling with physical principles to enhance both accuracy and computational speed. The Euler neural network (ENN) and the Runge-Kutta 4th-order neural network (RK4NN) for fatigue life estimation are proposed. These approaches are validated by comparing the results of rainflow counting with wind turbine damage ratios, demonstrating the accuracy achieves errors within 15 % for over 74 % of cases in the numerical stability range. Moreover, the RK4NN displayed superior generalization and fitting capacities across varied load conditions, effectively capturing early-stage damage growth while avoiding overfitting with the mean squared error 1.99 × 10<sup>−36</sup>. Additionally, the ENN and the RK4NN achieved the acceleration ratio of 19.53 × and 19.38 × respectively in comparison with the modified rainflow counting method (RCM).

Results show that crack initiation primarily originates from surface or near-surface regions, particularly near inclusions and Fe-rich particles. Crack initiation tends to be single-source at low stress levels and multi-source at higher stress levels. SBs formation is closely associated with stress levels; as stress increases, SBs formation becomes more pronounced, and band spacing decreases. At low stress levels, significant crack deflection occurs due to single slip mechanism activation, while at high stress levels, multiple slip system activation results in a flatter fatigue crack propagation (FCP) path. Early-stage FCP of Al-Li alloys under HCF exhibits small crack characteristics. The formation of fatigue striations in small cracks is influenced by the degree of work hardening at the crack tip, and the spacing of fatigue striations decreases with increasing stress levels.

The results indicate that the TMF life decreases as the peak temperatures rise from 400 °C to 500 °C. As the cyclic number increases, the maximum tensile stress shows slight cyclic hardening in the temperature range of 100 to 400 °C. Additionally, in the temperature range of 100 to 500 °C, the maximum compressive stress exhibits slight cyclic softening. The fatigue damage and crack propagation processes demonstrate that the tearing of vermicular graphite at the edge of the sample is the primary cause for fatigue crack initiation in the lower temperature range. The weakening region comprised of multiple vermicular graphite particles facilitates the gradual extension of cracks. At higher peak temperature, oxidation rapidly erodes the interface between the vermicular graphite and the matrix, which leads to the debonding of graphite and initiation of the fatigue cracks. The rapid oxidation effect accelerates the corrosion of the metal matrix, promoting crack propagation, which is the primary factor contributing to the reduction of fatigue life. Given the complexity and high cost associated with the TMF test, a method for predicting the TMF life by building the correlation between low-cycle fatigue and the TMF lives in terms of the hysteresis energy is proposed. This method enables rapid and accurate prediction of the TMF life through a relatively small amount of samples and simpler experiments, demonstrating significant industrial application potential.</div></div>","PeriodicalId":14112,"journal":{"name":"International Journal of Fatigue","volume":"197 ","pages":"Article 108931"},"PeriodicalIF":5.7,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143644062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The attention-based fusion mechanism enables adaptive integration of temporal and material features, enhancing the model’s ability to capture complex interactions between loading conditions and material characteristics. To validate this approach, a multiaxial fatigue dataset comprising 499 data points was established across six major categories of metallic materials. The model’s performance underwent rigorous evaluation using hierarchical nested cross-validation, while key features were identified through SHAP analysis and recursive feature elimination. Results demonstrate that the proposed unified model exhibits robust predictive performance, with TCN showing superior stability and efficiency compared to other temporal feature extraction methods.
