In independent of extensive investigations to mention fatigue theories, the problem of completing the extent of fatigue damage and then displaying fatigue life still remains a package challenge in fatigue perspective design.

Therefore, a reliable insistent damage rule is not expected in. Moreover, a diet for fatigue reliability assessments and service affordable prediction is presented based on the conclusion of the evolution and reputable distribution of fatigue damage over time.

The proposed methodology is then proved by experimental data obtained for a textbook axle (45 steel and LZ50 steel).Cited by: In this definition, fatigue in general and some interesting theories concerning theme of cumulative fatigue damage are discussed.
