The use of hysteresis loop measurements for assessing the constituent properties of unidirectional CMCs is evaluated, using basic theory described in a companion paper. Results are obtained on SiC/CAS and SiC/SiC composites. These materials exhibit very different hysteresis characteristics, reflected in differences in sliding stress, {tau}, and debond energy, {Lambda}{sub i}. These interface properties are manifest in the respective tensile stress/strain curves.
