摘要：
A modified cyclic cohesive zone model (CCZM) is proposed for predicting the fatigue crack initiation (FCI) life of mooring chain steels where the accumulated cohesive length in the damage evolution law is assumed to be a power function of normalized normal separation. The validity of the proposed CCZM is demonstrated by the comparison between model prediction of the proposed CCZM and a traditional CCZM, and experimental data of FCI lives of R4 and R5 grade mooring chain steels. The results indicate that the FCI lives predicted by the proposed CCZM are in good agreement with the experimental data.
