Abstract:

The experimental portion of the study involved two test specimen geometries and ten orthotropic graphiteepoxy laminates. The test data also show that the fracture toughness of an orthotropic fiber-dominated laminate may be predicted with some simple lamination theory models. The analytical results show that both the hole geoemtry and the laminate properties influence crack behavior. The results do not lend themselves to simple separation of these effects.
