It is thought that the classical fatigue equation is empirical and its mechanical implications are unknown. In this paper the authors study the fatigue failure of beam bending by means of damage mechanics. The amplitudes of initial undamaged stress and effective stress are used as controlling variations of damage development respectively to obtain the engineering closed solutions of fatigue crack initiation life which are equivalent to one another. The two closed solutions are also equivalent to those of the classical fatigue empirical formula. This is shown clearly that the classical fatigue empirical formula can be derived from the damage mechanical theory and its mechanical implications can be obtained consequently.
