　　A comparative study on two fatigue assessment methods has been performed in this paper.The analysis theory and method were discussed first and a comparison of their differences and relations were made.For comparison, direct calculations of fatigue life using two methods were performed respectively.At present, many organizations choose S-N curve method for calculation;but with the improvement of fracture mechanics, it will be more popular in the future.

基于S-N曲线和断裂力学的疲劳评估对比研究
本文对两种结构疲劳寿命的评估方法进行对比研究，从理论和分析流程等分别进行对比阐述，对两者的区别与联系进行总结。本文通过有限元实例展示了采用S-N曲线法与断裂力学法分析的差异。目前对于疲劳的评估，很多机构选择的还是S-N曲线法，但随着断裂力学研究的进一步发展完善，在未来将受到更多的关注。
