Apparatus for initiating fatigue related damage on a member |
摘要 |
Apparatus is disclosed for initiating fatigue related damage on a circumferential surface of a rotatable member resultant from application of a tensile stress condition and a superimposed contact stress condition. The apparatus includes structure for supporting the member for axial rotation, structure for applying a load to the member during the rotation thereof to create a bending moment at a predetermined axial location along the member and a resultant tensile stress condition on a circumferential surface thereof at a corresponding location. The apparatus further includes structure for creating a contact stress on the circumferential surface of the member at the predetermined location.
