Machine learning-based fatigue lifetime prediction of structural steels
Alexandria Engineering JournalFatigue of materials stands as a prevalent cause of mechanical structure failures, which often occur suddenly, unpredictably, and catastrophically. Accurately predicting the fatigue lifespan of materials is crucial, especially given the potential for ...

Probabilistic temporal extrapolation of fatigue damage of offshore wind turbine substructures based on strain measurements [PDF]
Wind Energy Science, 2022 Substructures of offshore wind turbines are becoming older and beginning to reach their design lifetimes. Hence, lifetime extensions for offshore wind turbines are becoming not only an interesting research topic but also a relevant option for industry ...

Equi-biaxial loading effect on austenitic stainless steel fatigue life [PDF]
Fracture and Structural Integrity, 2016 Fatigue lifetime assessment is essential in the design of structures. Under-estimated predictions may result in unnecessary in service inspections. Conversely, over-estimated predictions may have serious consequences on the integrity of structures.

Taking into account the non-proportional loading effect on high cycle fatigue life predictions obtained by invariant-based approaches [PDF]
MATEC Web of Conferences, 2019 Industrial structures are often subjected to multiaxial fatigue loadings. If the multiple stress signals are not synced the loading is said to be non-proportional.

From wind to loads: wind turbine site-specific load estimation with surrogate models trained on high-fidelity load databases [PDF]
Wind Energy Science, 2018 We define and demonstrate a procedure for quick assessment of site-specific lifetime fatigue loads using simplified load mapping functions (surrogate models), trained by means of a database with high-fidelity load simulations.

Critical length parameter of HDPE and its use in fatigue lifetime predictions
Fracture and Structural IntegrityThe contribution describes the fatigue lifetime predictions of polyethylene notched specimens based on the theory of critical distance. The approach uses the line method, which averages the axial stress over the critical distance.

A Fatigue Lifetime Prediction Model for Aluminum Bonding Wires [PDF]
Metals, 2023 Electrical signal transmission in power electronic devices takes place through high-purity aluminum bonding wires. Cyclic mechanical and thermal stresses during operation lead to fatigue loads, resulting in premature failure of the wires, which cannot be reliably predicted.

Fatigue lifetime prediction methodology of rubber components [PDF]
WIT Transactions on The Built Environment, 2008 Interest in the useful lifetime for rubber components increases where the extension of a warranty period is considered. Fatigue analysis and lifetime evaluation are very important in design procedures to assure the safety and reliability of automotive rubber components.

PREDICTION OF FATIGUE LIFETIME OF NOTCHED MEMBERS [PDF]
Fatigue & Fracture of Engineering Materials & Structures, 1979 Abstract— A simple model for the estimation of the total fatigue life of notched members is presented. The number of cycles to failure is estimated as the summation of the cyclic life spent in: (1) the initiation of a dominant fatigue crack at the notch root; (2) the very early growth of this crack within the notch plastic zone; (3) the subsequent ...
