Research output: Contribution to journalConference articlepeer-review


The generalized method of cells, an interfacial constitutive model and a probabilistic strength model are combined to yield an approach for modelling the interfacial stress-strain response of fibrous composites with fiber/matrix interfacial damage. It has been shown that the limitations of a single repeating cell in representing the response of a composite with debonding interfaces can be overcome through the introduction of a probabilistic interfacial strength. Predictions using this approach for the transverse tensile and axial shear response of unidirectional silicon-carbide/titanium recover the experimental results as required by the method.
