A novel finite element modelling approach is presented which incorporates representative binder yarn compaction, for simulating the low-velocity impact (LVI) and compression after impact (CAI) response of 3D woven layer-to-layer carbon/epoxy composit

A finite element mesh , aligned along the fibre direction, has often been purported to yield more accurate results in the modelling of damage in composite structures constructed from unidirectional fibre reinforced polymer laminates. However, there h

Previous works have established strategies to model artificial test lightning plasma with specific waveform parameters and use the predicted plasma behavior to estimate test specimen damage. To date no computational works have quantified the influenc

Lightning strike simulations have used decomposition models, derived from TGA experiments, to model material behaviour at elevated heating rates and temperatures. Such experiments, conducted non-isothermally and at low heating rates, are extrapolated

This paper examines the influence of edge glow effects (arcing of current from specimen side surfaces) on the prediction of material failure during an artificial lightning strike. A novel modelling approach is proposed to incorporate edge glow effect

Aircraft are increasingly being made of electrically resistive composites, rather than conductive metals. Therefore, it is important to analyse the damage caused by a lightning strike. Given the benefits of simulations over experimental analysis in t
