Abstract

A numerical homogenisation procedure is developed to predict the effective material properties for a carbon fibre-epoxy composite material. The method is shown to predict accurately the elastic response of the composite by comparison with previously published data. The effects of matrix plasticity on the shear and tensile behaviour of the composite are analysed. Matrix plasticity is shown to be significant in predicting the highly non-linear in-plane shear behaviour of the material and also improves the prediction of material stiffness under transverse tension.
