Fatigue failure is characteristic of components subjected to variable stresses over time and results in failures even when stresses below the material's resistance limit are used. Regarding fatigue failure, we CANNOT say that:

It is responsible for about 90% of all metal failures.
Fatigue failure is of the brittle type, with little plastic deformation.
Fatigue failure occurs through the slow and marked plastic deformation of the material until it breaks.
Fatigue failure affects polymers and ceramics.
It occurs suddenly and without warning.
