Abstract
In most engineering structures, fracture often takes place due to fatigue. Therefore, many studies about the effect of the various mode-mixities on fatigue characteristics have been performed. However, most of the former studies only address metal/metal interfaces or delamination of composite. In this study, the fatigue characteristics of composite/metal interfaces are investigated. The fatigue tests were performed using single leg bending(SLB)specimens that comprise composite and steel bonded to each other using co-cure bonding method. This paper focuses on fatigue characteristics depending on different mode ratios$(G_{II}/G_T$. The overall results obtained in this study show that the crack propagation rate increases with the mode II loading component.
