摘要

A multiphase model is developed for the analysis of the macroscopic behaviour of composite materials constituted of an elastic matrix reinforced with continuously oriented fibres exhibiting a softening behaviour. The model is then performed to develop analytical and semi-analytical solutions for solid structures subjected to uniaxial loadings (oedometric test and traction test) and flexural loading, showing the capacity of the model to quantify the macroscopic softening behaviour of such a composite material.
