Mixed-mode fracture of adhesively bonded metallic joints under quasi-static loading
This work uses a novel experimental configuration for the assessment of mixed mode fracture properties of adhesives under cyclic loading. The geometry is analysed through a combination of closed-form and finite element methods and it is shown that the elastic energy associated with the adhesive bond line has a significant affect on the fracture mechanics analysis. With this effect accounted for properly, the paper presents a comprehensive set of mixed mode fatigue test data for an important commercial adhesive (FM73), which may be used directly in fracture mechanics based models for crack propagation in adhesive joints.
