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.
