Forecast of the fatigue crack initiation site of commercially pure Titanium miniature specimens with local surface topography data [PDF]
MATEC Web of Conferences, 2020 Surfaces of technical components rarely appear in perfectly smooth condition. During fatigue loading, stress concentrations at surface asperities cause localized plastic deformation that can lead to crack initiation.
