Abstract Experimental study has been carried out on the effects of the com-plex strengthening of the cold expansion of hole (CEH) and overloading on the fa-tigue crack initiation life (FCIL) of LY12CZ alloy The overloading has noappreciable effect on FCIL of LY12CZ alloy after CEH. Moreover, an expressionfor FCIL of LY12CZ alloy subjected to the complex strengthening is given. Basedon the above-mentioned results, a new method is put forward to predict theFCIL of LY12CZ alloy after CEH under variable amplitude loading and has beensubstantiated by the fatigue tests under a flight-to-flight spectrum.
