Abstract
The effect of hybridization on the interface crack growth along the fiber is predicted from numerical and analytical modelling approaches. A three-phase hybrid composite representative volume element (RVE) with an adjustable hybrid ratio and an initial interfacial crack is modelled. The fracture parameters and composite strength are computed from finite element analysis using VCCT approach in Ansys Workbench. A fracture energy-based mathematical model with a steady state crack growth is implemented to compute the hybrid composite splitting failure strength. The results show an enhancement in the compressive splitting strength with hybridization due to lateral confinement effect on the interfacial crack.
