| Abstract: | The detail stresses of the riveted structure are analyzed under the eccentric load by the combination of the Finite Element Method and the Theory of the Engineering Beam first, and then, its fatigue dangerous position is determined. The stress severity factor method is used to calculate the fatigue life of the structure. In the end, the experiment of the simulated structure shows that the result is consistent with the analytic result of the theory. |
