Self-similarity of damage-failure transition and the power laws of fatigue crack advance
Fracture and Structural IntegrityWe propose the interpretation of the Finite Fracture Mechanics based on the criticality of damage-failure transition due to specific metastability of free energy release.

steel research international, EarlyView.Surface reconditioning through mechanical and electrochemical polishing is shown to extend the fatigue life of predamaged 42CrMo4 steel by over 12 times. By removing ≈100 μm of surface material, surface‐driven fatigue damage is mitigated. This study introduces a reuse potential metric to evaluate fatigue recovery and support sustainable steel reuse. To

Effect of Loading Frequency on the Fatigue Response of Adhesive Joints up to the VHCF Range
Applied Sciences, 2023 Modern structures are designed to withstand in-service loads over a broad frequency spectrum. Nonetheless, mechanical properties in numerical codes are assumed to be frequency-independent to simplify calculations or due to a lack of experimental data ...

Microstructure, Defects, and Fatigue Response of High‐Strength Tool Steels
steel research international, EarlyView.The martensitic tool steel family is designed for use in various working environments where they are subjected to repeatedly high mechanical loads. Despite the continuous upgrade of material´s microstructures through compositional development or processing techniques, defects remain a critical factor for the tool performance by leading to fatigue ...

Comparison between Fractal and Statistical Approaches to Model Size Effects in VHCF
Metals, 2022 Size effects concern the anomalous scaling of relevant mechanical properties of materials and structures over a sufficiently wide dimensional range. In the last few years, thanks to technological advances, such effects have been experimentally detected ...

Applied Stochastic Models in Business and Industry, Volume 42, Issue 2, March/April 2026.ABSTRACT Fatigue is the most common reliability failure mechanism and has been studied widely since the 19th century. Material specimens are used in laboratory experiments to obtain fatigue test data. An S‐N curve is used to depict the relationship between the stress (or strain) S$$ S $$ and the number of cycles to failure N$$ N $$. Statistical methods

ChemElectroChem, Volume 12, Issue 20, October 16, 2025.Structural modification of ZnHCF cathodes via ball‐milling and carbon addition significantly enhances the electrochemical performance of aqueous zinc‐ion batteries, achieving capacities close to 100 mAh g−1. The synergistic effect of carbon with ZnHCF preserves the crystalline structure and facilitates phase transitions, greatly improving the cathode's
