在文献分析的基础上，总结了一种直接、一致地评价陶瓷基复合材料组成性能的方法。结果提供了一个能够模拟这些材料的应力/应变行为的本构律。该方法用两种cmc的数据来说明：SiC/CAS和SiC/SiC。组分性质也被用作表征应力再分布和预测应变浓度对宏观性能的影响的力学过程的输入。
A methodology for the straightforward and consistent evaluation of the constituent properties of ceramic-matrix composites (CMCs) is summarized, based on analyses from the literature. The results provide a constitutive law capable of simulating the stress/strain behavior of these materials. The approach is illustrated using data for two CMCs: SiC/CAS and SiC/SiC. The constituent properties are also used as input to mechanics procedures that characterize stress redistribution and predict the effect of strain concentrations on macroscopic performance.
