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.

Civil Engineering Design, 2021 The residual structural lifetime of concrete bridges is often limited by fatigue of the prestressing steel. In practice, numerical calculations of the structure are combined with Miner's rule—based on load frequencies and stress amplitudes—to estimate ...

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 ...

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.

Fatigue Lifetime Prediction of Laminated Composites a Review
International Journal of Recent Technology and Engineering (IJRTE), 2020 It is evident that laminated reinforced composite are successfully prolonging the life of composites compared to particle and fiber type of reinforced composites method. The question on how these laminated composites take up the fatigue loading is crucial in order to give sound confident to industry replacing their design from metal to composites based.

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.
