摘要
以工程上常见的带小孔的有限宽度薄板为模型,采用ANSYS有限元软件对其进行了应力分析,采用局部应力应变法对其进行了疲劳寿命分析计算,根据计算结果可知,对于所给定的薄板模型,重复工作100次即达到了疲劳寿命。
The stress of the familiar sheet with finite width and small hole was analyzed by ANSYS.The fatigue life was calculated with the partial stress and strain method.According to calculated result,the given sheet would reach its fatigue life by repeated working for 100 times.
