N2 - This study presents an application of fracture mechanics to determine interfacial mixed-mode fracture properties of adhesively bonded aerospace material systems using the numerical and experimental methods. Using the finite-element results, correction factors were applied to the specimens with different adherends and a polynomial fit was proposed to evaluate the stress intensity factors of a modified version of Arcan specimen with an interface crack subjected to mixed mode loading. The finite element analyses of bonded joints were also studied for various materials, thickness of adhesive and different crack length along the interfaces. The mixed-mode fracture toughness tests were carried out by using specimens consisting of several combinations of adhesive, composite and metallic adherends over a wide range of loading angles. Stress intensity factors and associated energy release rates were obtained for various cases of interest. The result of fracture toughness tests reveals that the interfacial fracture of bonded joints is strong to the shear loading but weak to the normal loading.
