| Abstract: | In this paper, the distribution of the corrosion damage characterization factors was analyzed through the accelerated corrosion test and fatigue test date. The methods of application of neural network and Monte Carlo in material fatigue life prediction and reliabi problem result from the randomicity in corrosion fatigue lity of analysis provided a reference for an engineering h between the analysis results and the experimental results could igh be strength aluminum alloy. The relative error accepted in the project |
