摘要

摘要: 研究了E-glass/epoxy机织复合材料的失效破坏过程及预测该材料的失效强度。模型基于复合材料微观力学对机织复合材料进行均化处理从而获得材料的宏观特性。该模型考虑了材料失效，并在失效发生时对材料进行退化处理。该过程由用户材料子程序实现。利用这一模型可很好地研究材料失效过程，预测材料的失效强度，得到与实验结果相符的应力应变曲线。

Abstract: This paper focuses on the E-glass/epoxy woven composite materials' progressive failure analysis and strength prediction. The model for the woven composites' macro-properties is obtained based on the micromechanics of composite materials and with homogenized method. This model also considers the damage criteria, and the material properties will be degraded and updated when damage occurs. This procedure is achieved by user material codes (ABAQUS.VUMAT). This model can easily trace the progressive failure behavior, predict failure strength, and finally obtain strain stress curves which can perfectly match experimental curves.
