Book excerpt: The objective of this investigation is to develop constitutive and failure models for composite materials based on observed damage mechanisms and damage development. Unidirectional continuous-fiber ceramic matrix composites were investigated under longitudinal and transverse loading. Failure mechanisms and their development were studied in real time under the microscope. Micromechanical analyses were conducted and stress distributions were obtained in the constituents and around matrix and interfacial cracks. The influence of the interphase region on stress strain relations and failure properties was studied. A modified shear lag analysis yielded stress strain relations to failure and relations between applied stress, matrix cracking and fiber-matrix debonding.
