Based on the theory of damage mechanics, a method for fatigue crack initiation life prediction of
notched components is proposed in this paper. The damage evolution equation of notched specimen under tensioncompression
loading is obtained in term of closed-form solution. The crack initiation life of notched specimen is
estimated by the proposed method even when material and stress concentration factor are different. It has been
verified that the result calculated by the proposed method agrees with the experimental result. The proposed
method is concise, effective and feasible to practical application.
