摘要
采用疲劳寿命计对复合材料层板的疲劳过程进行了监测,研究了复合材料层板在单级和多级载荷下的疲劳累积损伤与疲劳寿命计电阻变化之间的关系。结果表明疲劳寿命计的输出电阻的累积变化能较好地反映层板的疲劳状态。
The fatigue process of composite laminates is monitored with S/N fatigue life gages (FLG). The relationship is established between the status of the damage in composite laminates and the output of the S/N fatigue life gages. The results show that the change of the cumulative resistance reflects the fatigue status of the composite laminates and this method is used for monitoring fatigue course of structures.
