Computational micromechanics of fatigue of microstructures in the HCF–VHCF regimes [PDF]
International Journal of Fatigue, 2016 Abstract Advances in higher resolution experimental techniques have shown that metallic materials can develop fatigue cracks under cyclic loading levels significantly below the yield stress. Indeed, the traditional notion of a fatigue limit can be recast in terms of limits associated with nucleation and arrest of fatigue cracks at the microstructural

Influence of artificial seawater on the VHCF behavior of different steels
Fatigue & Fracture of Engineering Materials & Structures, 2022 AbstractThe fatigue properties of a high‐strength steel, a structural steel, and a duplex stainless steel in artificial seawater were investigated. Consequently, a test chamber for the existing ultrasonic test stand was implemented. The experiments were performed with smooth specimens at a loading with R = −1 up to 2 · 109 cycles.

Crack propagation mechanism and life prediction for very-high-cycle fatigue of a structural steel in different environmental medias [PDF]
Fracture and Structural Integrity, 2013 The influence of environmental medias on crack propagation of a structural steel at high and very-high-cycle fatigue (VHCF) regimes is investigated based on the fatigue tests performed in air, water and 3.5% NaCl aqueous solution.
