基于格林函数和有限元分析的多尺度方法模拟SiC/IMI834复合材料拉伸试验,研究复合材料微区应力分布、宏观力学性能和纤维失效情况.其中有限元分析用来计算SiC/IMI834复合材料微区应力分布并为格林函数提供应力传递集中因子.格林函数用来模拟SiC/IMI834复合材料宏观失效过程及力学性能.结果表明,失效纤维上应力恢复区长度受材料性能影响,与外加载荷无关；距离失效纤维越远,沿失效端面纤维上轴向应力越低；距离失效纤维越近,沿失效端面基体上轴向应力越低；SiC/IMI834复合材料宏观失效应变随纤维体积分数增加而提高,但SiC/IMI834复合材料初始纤维失效与纤维体积分数无关,拉伸应变均为0.01.
