摘要
三维编织复合材料的模型是计算机辅助设计复合材料的基础 ,但是目前的研究还很不成熟。本文应用三维编织复合材料的单胞模型 ,应用有限元分析软件ANSYS模拟了三维编织复合材料的编织结构 ,并模拟了得到了复合材料拉伸时的位移场和应力场 ,并由ANSYS的应力和应变结果计算了复合材料的等效弹性模量。其计算结果与实验结果符合较好。
Computer aided composites design are based on the modeling of 3D braided composites. But the study of modeling of composites is very not mature. In this paper, unit cell modeling of 3D braided composites is applied. Braided structure, displacement field and stress field are stimulated by using FEA software ANSYS. Composite moduli are calculated due to results of stress and strain. The predicted results of moduli are in good agreement with experiment results.
