层板复合材料疲劳性能测试实验

Experimental Technology for Fatigue Behaviour Testing of Composite Laminates

根据层板复合材料的性能与具体的铺层形式有关的特点 ,介绍了在层板复合材料疲劳性能测试中试件准备注意事项、疲劳性能测试的内容和实验控制程序的要求 ,以及为缩短实验时间、优化层板复合材料疲劳剩余强度和疲劳剩余刚度分析模型的参数估计 ,并减少测试所需试件数量的合理试件数的确定方法 .

For testing of the fatigue behavior of various types of composites laminates,this paper introduces in detail how to prepare the specimens,the contents of fatigue testing,the requirements for experimental control and the method for reducing experimental time and the total number of specimens for determination of rational numbers of specimens,optimizing parameters estimation in the analysis models of fatigue residual strength and fatigue residual stiffness.
