A theory for predicting the ultimate tensile strength of a unidirectional ceramic-matrix composite subjected to uniaxial tension is presented. Of particular interest are composites that sustain multiple matrix cracking with increasing load. Damage beyond the point of matrix crack saturation is assumed to be primarily associated with fiber breakage. An analysis is carried out of the distribution of fiber breaks and their influence on the diminished bad-carrying capacity of the composite. Variables of particular interest include the interfacial shear strength, the strength of the fibers, and their variability.
