For the investigation of fracture criteria, adhesive tensile strengths of scarf and butt joints bonded by a brittle and two ductile epoxy adhesives have been measured and three-dimensional finite element analyses have been performed. Deformation of the joints influenced considerable by mechanical properties of adhesives. Fracture of the joints bonded by the brittle adhesive obeyed maximum principal stress criterion. In the scarf angles of 15° to 60°, fracture of the joints bonded by the ductile adhesives obeyed von Mises criterion and in the scarf angles more than 60°, brittle (cleavage) fracture occured for those joints by plastic constraint due to increase of stress triaxiallity in adhesive layers. Locations of fracture initiation and fracture modes of adhesive layers observed with an optical microscope and a a scanning electron microscope agreed with those expected from experimental results of deformation and adhesive tensile strength, and results of stress analyses.
