Abstract : Mixed-mode matrix fracture in notched off-axis undirectional composite is investigated. First the problem is treated by an exact formulation based on elastic fracture mechanics. It is then simulated by a finite element model. Correlation with experiment suggests a fracture criterion based on total strain energy release rate as the fracture parameter. Keywords: Composite material, Graphite epoxy, Mixed mode fracture matrix cracking, Singular integral equation, Finite element simulation, Experiment analysis correlation.
