A micromechanics framework for modelling the longitudinal failure of unidirectional fibre composites, in both tension and compression, is presented. Appropriate constitutive models are used for the different constituents (i.e., fibre and matrix) and

Interlaminar crack onset and propagation in fibre-reinforced composites is here investigated in detail through the development of a micromechanics framework. The different dissipative effects that characterize crack propagation are assessed by using

An algorithm to create a representative volume element (RVE) of a unidirectional composite material with a random distribution of reinforcements is detailed in this chapter. The generated distributions are validated for their randomness using statist

Initial fibre misalignment is recognised to be one of the precursors leading to longitudinal compressive failure in fibre-reinforced composites. Thus, to properly model their mechanical behaviour, an accurate spatial representation of the fibrous rei

Resin-rich areas in composite laminates can occur as inter-laminar resin ‘layers’ between plies or as intra-laminar resin ‘pockets’ within a single layer. In this work, numerical methods are used to study the effects of resin pockets on the t
