Description

  • Content Description: In this study, the failure of the ductile layers from collinear and delaminating cracks that occur in laminated composite systems was studied using a constitutive relationship that accounts for strength degradation resulting from the nucleation and growth of voids. The results indicate that in laminated composites, void nucleation and growth ahead of the cracks occur at a much faster rate due to evolution of much higher stress values at the interface region. For delaminating crack cases, the fracture behavior is strongly influenced by the delamination length. The resistance of the ductile layers to crack extension can be significantly reduced by short delamination lengths.
