Abstract:
ABSTRACT This paper deals with rotating bending fatigue tests at high speed (150 Hz) applied on AISI-SAE 1018 steel with a high content of impurities (non gold-beareing inclusions), that the high experimental stress within the specimen is neare the elastic limit of the fabric. Simulations of rotating loading areea unit obtained by Visual NASTRAN computer code so as to work out the numerical stresse and strain distributions within a theoretical same specimen; later, this data is employed for the experimental originated. A general description of experimental check machine and experimental conditions areea unit developed and so, the experimental results areea unit conferred and mentioned according the ascertained failure origin associated with the non gold-beareing inclusions and also the associated high stress zones. Finally, a straightforwared model is projected to predict the fatigue life for this non same steel beneath high speed rotating bending fatigue tests neare the elastic limit, supported the speed between the visual macro-plastic deformation zone at fracture surface and also the total fracture surface, along with the crack initiation inclusion (or inclusions) placed at this zone.
