本文介绍单向复合材料梁在慢速和冲击加载条件下三点弯曲的实验结果以及对材料损伤机理和破坏模式的分析,提出了一种考虑损伤过程的有限元数值模拟方法,并根据该方法对材料性能进行预估,结果与实验结果符合较好。
In this paper, the experimental results of three-point bending of unidirectional composite beam under slow and impact loading conditions and the analysis of damage mechanism and failure mode of the material are introduced. A finite element numerical simulation method considering the damage process is proposed. According to the method The material performance is estimated, the result is in good agreement with the experimental results.
