The methodology non–destructive test inspection by ultrasound for predict the beginning of the failure of a material subject to rolling contact fatigue

Abstract

The methodology of inspection of the non-destructive testing by means of ultrasound was proposed and implemented to predict the beginning of the failure of an element under rolling contact fatigue, since it is not counted on norms that specify it. For this purpose a series of instructions appears step by step that are necessary to follow to make a reliable inspection by means of the ultrasound technique, using as foundation that is established in ASME BPVC section V code. An artificial reproduction of the fatigue failure by rolling contact in steel material was used, with the purpose of verifying the feasibility of the developed methodology, in replacement of a fatigue test of contact in tribometer of pending execution. Keywords: ultrasound, rolling contact, fatigue, tribology.
