| Abstract: | Situations of model establishment of riveted structural parts in aircraft and selection of parameters were introduced.The coefficient of stress concentration Kt of rivet hole was calculated by adopting soft wares of SOLIDWORKS and COSMOS.After that the fatigue life of connector was computed by applying Neuber method and identical method of stress-work.The result showed finally that it may simplify the process of computation by applying CAD/CAE technology,and may enhance the accuracy of computing the fatigue life by means of the modification on Kt value. |

| Keywords: | rivet hole coefficient of stress concentration finite element method computer aided engineering |
