Fiber reinforced ceramic matrix composite (CMC) display nonlinear mechanical behavior related matrix microcracks and various internal effects. Model of that behavior is an efficient tool on a structural analysis scale. On/Off-axis tension/compression and losipescu shear experiments of 2-D plane woven NUSK-CMC are carried out to obtain the nonlinear mechanical behavior. From the data, a damage mechanical model about CMC's nonlinear mechanical behavior has been developed according to the continuum damage theory. This report presents experiment result of Open whole tension tests and bending test of I-beam. And FEA results of those experiments. The results proof that damage model is very effective..
