Generation of random distribution of fibres in long-fibre reinforced composites

This paper presents a new model to the generation of the transversal cross-section of long-fibre reinforced composites with high fibre volume fraction, characterised by a random distribution of the reinforcements. This stochastic nature has a significant influence on the microscopical distribution of stresses and strains and therefore on damage initiation and subsequent propagation. A simple and fast algorithm ...

A three-dimensional damage model for transversely isotropic composite laminates

This article proposes a fully three-dimensional continuum damage model, developed at the sub-ply level, to predict in an integrated way both the intralaminar and the interlaminar failure mechanisms that occur in laminated fiber-reinforced polymer composites. The constitutive model is based on the assumption that the composite material is transversely isotropic, and accounts for the effects of crack closure unde...
