Unformatted text preview: stress applied to the material. In consequence, the Hertz’s critical tension is modified and the ultimate stress or fatigue limit of the material may be exceeded. An industrial case is used to illustrate this assertion. Keywords: Specification uncertainties, performance, Stress, Hertz contact 1. INTRODUCTION I nspection uncertainties, Operating In the Eighties, the improvement of the quality of manufactured products has been the goal of a great number of research teams working on various complementary topics. The metallurgists have therefore developed enhanced methods and processes guaranteeing the properties of the manufactured alloys. This advanced metallurgy permitted controlling the behavior of the material under loading. New dimensioning methods have also been proposed by the mechanic al research teams. A better characterization of the stress state of each part and of its damage mechanisms was thus obtained. The geometr ical precision of the parts has been improved too, introducing numerical control technologies in the manufacturing processes. A substantial progress of the quality of the manufactured products ha...
