Fatigue analysis
Fatigue is one of the important material properties where the
component subjected to cyclic loading. Due to cyclic loading, the
materials undergone stress and nucleate micro cracks essentially
on the surface of the component. It is understood that tensile
stress is always assisted in nucleation and propagation of cracks
and leads to failure. In the present investigation S-N curve
(fatigue curve) is generated through FE analysis for the material
used in the present investigation. It is noted from the Figure 11
that for high cycle fatigue test, of the material selected in the
present study, the endurance stress is found 90 MPa which is
well below the yield stress of the material.
