2. Fatigue of Steel Structures Fatigue failure may occur when a cyclic tensile stress is applied to a component or structure. Failure is progressive, each stress cycle causing incremental growth of the fatigue crack. Fatigue crack surfaces are often characterised by regular steps, each step being due to the crack growth during one cycle.

The macroscopic analysis of the shaft showed that the failure is of fatigue however closer microscopic Those materials tend to fail suddenly and abruptly without showing any sign of plastic deformation. Concrete and glass are 2 examples of brittle materials. Note that you have also materials which a ductile up to a point and then become brittle. Some materials like bone can be ductile or brittle in function of the strain rate (Source) View Examples on Fatigue Failure.pdf from ME 340 at San Diego State University.
