| Abstract: | The experimental studies of "detail fatigue ratings cutoff (DFRcutoff)" of LY12CZ,LC4CS aluminum alloy and 30CrMnSiA steel commonly used in aircraft structures were conducted in different environment and aircraft structure durability design were provided with important experimental data. The program demonstrated that the effects of different environment oh material life are different laboratory air moist air and 3.5% NaCl solution are listed in order of increasing potency. |
