Abstract:
In this paper a simplified discrete finite element model for composite materials
is introduced. This model allows the discrete representation of both the fibre
tows and the resin on a meso-scale level. The capability to assign different
material properties to each fibre tow and resin zones allows the investigation
of local reinforcements in composites. This modelling concept is combined with a
three dimensional damage model and is successfully implemented in a finite
element code. Results indicate that relatively fast model analysis and
successful approximation of fibre and resin failure under specific load cases
may be investigated.
