Modelling and characterisation of dynamic behaviour of short-fibre-reinforced composites

This study proposes a constitutive model of viscous behaviour of short-fibre reinforced composites (SFRC) with complex distributions of fibre orientations and for a wide range of strain rates. The model is based on an additive decomposition of the state potential for the computation of composite macroscopic behaviour. Thus, the composite material is seen as the assembly of a matrix medium and several linear elastic fibre media. The division of...
