| titleOfInvention | Method of assessing rolling contact metallic material shear stress fatigue values, and method and device using same that estimate fatigue limit surface pressure |
| abstract | A method of assessing rolling contact metallic material shear stress fatigue values comprises the steps of deriving, by an ultrasound torsion fatigue test, a relationship between a rolling contact metallic material shear stress amplitude and a load cycles (S1); and determining, from the relationship between the shear stress amplitude and the load cycles derived in the test step (S1), a shear fatigue strength tau lim in an extended longevity region according to a set reference (S2). The ultrasound torsion fatigue test is a complete alternating torsion fatigue test, which applies torsion oscillation to a test part (1), wherein the torsion oscillation is such that the torsion is symmetrical in the positive rotational direction and the inverse rotational direction. |
