... to assess the role of friction in subsurface fatigue cracking in rolling-sliding contact applications. Based on the results of stress calculations and x-ray diffraction testing of steel samples, friction contributes to subsurface damage primary through its effect on the distribution of orthogonal shear...

... FATIGUE (RCF) is a common failure mode in components subjected to rolling or rolling-sliding contact (e.g., rolling-element bearings, railway tracks, gears). It is characterized by crack propagation caused by the near-surface alternating shear stress field, caused by rolling or rolling-sliding contact...
