Failure mechanism of bonded joints with similar and dissimilar material

Adhesive joints with dissimilar materials have gained substantial attention recently due to their lighter specific weight compared to the joints with similar metallic components. In particular, dissimilar material joints with a structure such as composite materials combined with light-weight metals have been widely used in the automobile industries to overcome the issue of fuel efficiency and weight reduction. Therefore, accurate analysis and study about the mechanical behavior of dissimilar materials joints are fundamentally required. In this study, the experiments and finite elements analysis were performed on single lap-shear bonded joints with metal-composite, similar composites and dissimilar composites components to investigate the factors that affect the joint failure load.
