Abstract
A multiscale modelling technique has been developed to predict the strain rate dependent properties of a fibre reinforced composite system. The full stress–strain behaviour through yield of an amine cured epoxy resin matrix (tetraglycidyl 4,4′-diaminodiphenylmethane) has been predicted using group interaction modelling. These data are used in a three-dimensional finite element model to obtain strain concentration factors of fibres adjacent to a fibre break in a unidirectional composite. A Monte Carlo simulation is performed to predict the tensile failure strain of a single composite layer and by assembling these layers the ultimate failure strain of the composite system is predicted. The technique is repeated over three different strain rates and consistency with experiment is observed.
