【 摘 要 】

The use of bond joints has increased recently, owing to a number of advantages they have over mechanical fasteners. However, most relevant studies have focused on bond joints with the same adherends. In this study, a quasi-static tensile test was conducted to investigate the failure mechanism of bond joints, considering different overlap lengths and dissimilar adherends. In the experiments, two modes of failure were observed: the interfacial and cohesive failure modes. The experiments showed that the length of separation of an overlap area through the interfacial failure was almost the same for different specimens.
