摘　　要：针对纤维增强复合材料宏观力学性能计算,基于均匀化理论,结合有限元算法,建立纤维增强复合材料表征单元宏观等效弹性参数数值算法。将其应用于单向纤维增强复合材料等效模量的数值分析,得到六边形排列单向纤维增强复合材料等效模量随纤维体积含量的变化规律。结果表明:均匀化有限元方法数值解与理论解吻合较好,为复合材料性能预测提供了平均意义上更为精确的估计,可为宏、细观多尺度复合材料性能分析奠定基础。The homogenization finite element method was presented to predict the macroscopic mechanical pa-rameters of fiber reinforced composites based on the representative volume element. Then it was applied to cal-culate the efective mechanical parameters of unidirectional fiber reinforced composite material with hexagonal array. The elastic parameters of unidirectional fiber reinforced composites changed with fiber were obtained. Results show the numerical solution is agreed with the theoretical solutioaccurate estimate on average for predicting composite material property and is an efficient scale analysis of composite material.
