“…This follows experimental evidence of free surfaces or discontinuities triggering failure; for instance, in cross-ply CT specimens, failure starts at the 0 • /90 • interface and propagates inwards to the 0 • plies (Laffan et al, 2010, Pinho et al, 2006a. Beyerlein and Phoenix, 1996), this approximation is necessary to verify the discrete hierarchical failure process.…”

The translaminar fracture toughness of fibre-reinforced composites is a size-dependent property which governs the damage tolerance and failure of these materials. This paper presents the development, implementation and validation of an original analytical model to predict the tensile translaminar (fibre-dominated) toughness of composite plies and bundles, as well as the associated size effect. The model considers, as energy dissipation mechanisms, debonding and pull-out of bundles from quasi-fractal fracture surfaces; the corresponding lengths are stochastic variables predicted by the model, based on the respective bundle strength distributions and fracture mechanics. Parametric studies show that composites are toughened by stronger fibres with large strength variability, and intermediate values of interfacial toughness and friction. Predictions are validated against four different composite ply systems tested in the literature, proving the models ability to capture not only size effects, but also the influence of different fibres and resins.

“…Double-cantilever-beam (DCB) [25], four-point end-notched flexure (4ENF) [26] and Mixed-mode bending (MMB) [27] test configurations were used to determine initiation/propagation fracture toughness of mode I, mode II and mixed-mode respectively. Compact Tension (CT) and Compact compression tests (CC) [28,29] were employed to measure the longitudinal tensile and compressive fracture toughness. V-notched rail shear tests were employed to measure the non-linear behaviour and fracture toughness associated with shear loading [30].…”

The development of the latest generation of wide-body carbon-fibre composite passenger aircraft has heralded a new era in the utilisation of these materials. The premise of superior specific strength and stiffness, corrosion and fatigue resistance, is tempered by high development costs, slow production rates and lengthy and expensive certification programmes. Substantial effort is currently being directed towards the development of new modelling and simulation tools, at all levels of the development cycle, to mitigate these shortcomings. One of the primary challenges is to reduce the extent of physical testing, in the certification process, by adopting a 'certification by simulation' approach. In essence, this aspirational objective requires the ability to reliably predict the evolution and progression of damage in composites. The aerospace industry has been at the forefront of developing advanced composites modelling tools. As the automotive industry transitions towards the increased use of composites in mass-produced vehicles, similar challenges in the modelling of composites will need to be addressed, particularly in the reliable prediction of crashworthiness. While thermoset composites have dominated the aerospace industry, thermoplastics composites are likely to emerge as the preferred solution for meeting the high-volume production demands of passenger road vehicles. This keynote paper outlines recent progress and current challenges in the development of finite-element-based predictive modelling tools for capturing impact damage, residual strength and energy absorption capacity of thermoset and thermoplastic composites for crashworthiness assessments.

“…Therefore, plyblocking has been seen to result in extensive damage zones in multidirectional 10 laminates. This creates a substantial challenge when attempting to characterize the translaminar fracture of 0 • plies for different 0 • ply-block thicknesses, using cross-ply specimens [6,9,10].…”
