Abstract
Semi-elliptical shear-mode fatigue cracks were promoted in the axial direction of round
specimens of SAE52100 bearing steel by fully-reversed cyclic torsion tests under a static axial
compressive stress. Non-propagating cracks smaller than 1 mm were obtained in two ways; (i)
stress amplitude decreasing tests of notched specimens, or (ii) constant stress amplitude tests of
smooth specimens. The threshold stress intensity factor ranges, (KIIth and (KIIIth, showed a crack
size dependency.
