Special Issue Information

Dear Colleagues,

This Special Issue aims to bring together cutting-edge research addressing the challenges of fatigue in modern engineering systems. Contributions are invited on all aspects of fatigue behavior, including low-cycle fatigue (LCF), high-cycle fatigue (HCF), and very-high-cycle fatigue (VHCF), with particular emphasis on complex loading conditions such as multiaxial loading. The integration of artificial intelligence and machine learning into fatigue assessment, modeling, and prediction is especially encouraged.

Topics of interest include advanced experimental methods for fatigue characterization, failure analysis techniques, and innovative approaches in mechanical design that enhance structural integrity. Submissions exploring modeling strategies are welcome, from physics-based to data-driven frameworks, particularly when applied to emerging technologies such as additive manufacturing (3D AM).

We also seek contributions on digital twin concepts for real-time monitoring and life prediction of structures, enabling more reliable and efficient engineering systems. By combining experimental insights, computational modeling, and intelligent algorithms, we aim to advance the understanding and prediction of fatigue phenomena, supporting safer and more sustainable designs across a wide range of industries.

Based on the rotary bending loading principle, an experimental investigation into the fatigue properties of 6201 aluminum alloy individual wires is presented. Considering the long design service life, high-cycle fatigue (HCF) behavior, and slender geometry (high length-to-diameter ratio) of these wires, a high-speed [...] Read more.
Based on the rotary bending loading principle, an experimental investigation into the fatigue properties of 6201 aluminum alloy individual wires is presented. Considering the long design service life, high-cycle fatigue (HCF) behavior, and slender geometry (high length-to-diameter ratio) of these wires, a high-speed rotary bending fatigue test platform is custom-designed and constructed. The design mechanically maximizes the probability of fracture at the midpoint of the constant-cross-section specimen, even when considering clamping damage at the ends. Through mechanical derivation for the test platform, based on the beam bending theory and the finite element method, a quantitative relationship is established between the bending stress amplitude and the deflection angle at the clamped end. Using this platform, the fatigue lives of 6201 aluminum alloy individual wires under various bending stress amplitudes are tested, and the stress–life (S-N) curve is obtained. The developed experimental method and the reported fatigue data in this study provide essential experimental and material data for fatigue life prediction and engineering design of 6201 aluminum alloy individual wires.
