Abstract
This study presents an experimental and theoretical investigation into the bond-slip relation of a CFRP-to-steel bonded interface under cyclic loading. It was observed that the peak interfacial shear stress during cyclic loading was lower than that during monotonic loading. A damaged-plasticity-type bond-slip relation was developed to model the constitutive behavior of the bonded interface under quasi-static cyclic loading. This was further extended by developing a model for the damage accumulation rate to account for the damage evolution under fatigue cyclic loading. The predictions from the theoretical models were found to be conservative as compared to the experimental results.
