| 摘 要： | 0INTRODUCTION*Bolted connections are commonly found in machines and structures. Since fatigue of bolts is the principal failure mode of the bolted joints under cyclic loading，a reliable fatigue prediction methodology is necessary for the durability of the bolted joints.For a long time，some approximate methods have been used in the fatigue analysis for bolted joints，but the methods may sometimes overestimate or underestimate fatigue limits for bolts. This is because that the approximate…

| Abstract: | A cyclic plasticity model is used into finite element (FE) method to obtain the details of elastic-plastic stress-strain in the bolts under cyclic axial loading. Two criteria in multiaxial fatigue are employed to predict fatigue lives of bolts. The predicted fatigue lives are in favorable agreement with the experimental results for machined bolts. |
