提出了一种从应力/应变曲线评价陶瓷基复合材料(CMC)组成性能的方法。这些程序演示了界面特性和失配应变如何与卸载/重新加载滞后和永久应变相关。通过在两个CMC上获得实验测量，该方法在配对论文中得到了说明。结果表明，界面滑动应力和脱粘能的不同会导致应力/应变曲线形状的显著变化。
A methodology for assessing constituent properties of ceramic matrix composites (CMCs) from stress/strain curves is developed. The procedures demonstrate how the properties of the interface and the misfit strain can be related to the unload/reload hysteresis and the permanent strain. The approach is illustrated in companion papers by obtaining experimental measurements on two CMCs. The results demonstrate why differences in the sliding stress and the debond energy of the interfaces result in substantial changes in the shape of the stress/strain curve.
