| Abstract: |
| Within the range of small crack during analysis of aircraft structural durability under corrosion environment, the model of pre-corrosion crack initiation life influence coefficient at different crack sizes was studied. The data of (C,t) was fitted with four forms of function, and then the fitting results were compared and analyzed. The result showed that the single parameter exponent form of the function is the best and the slopes of these curves have no difference. |
