Abstract

In the present paper the effective mesoscale failure response of a ¿bre-epoxy sample is computed from its complex microscale fracture behaviour. The mesoscale failure response is represented by a traction-separation curve derived from numerically homogenizing the fracture response of a periodic ¿bre-epoxy microstructure loaded under uniaxial tension. The traction-separation curve can be applied in material points of interface elements that are used for simulating mode I mesoscopic fracture in macroscopic laminate failure problems. The size of the microscopic ¿bre-epoxy sample on the mesoscale failure response is examined, as well as the effect of local imperfections at ¿bre-epoxy interfaces.
