A finite element model of the deformation and failure of brittle matrix composites during matrix cracking and delamination has been developed. The model is underpinned by the micro-mechanics developed by Aveston, Cooper and Kelly, represented through a damage mechanics approach, in which the effect of individual cracks and fibres is smeared into a continuum response. The model allows matrix micro-cracking, shear, and tensile delamination to be modelled by intersecting failure surfaces in stress space. Comparison of the predictions by the finite element model with experiments shows promise for the analysis of critical engineering structures and components.
