A novel test set-up is presented for validation of hybrid connector models between steel and aluminium components subjected to static and impact loading. The proposed components consisted of two hat profiles in steel and aluminium joined by adhesive bonding combined with self-piercing riveting. The geometry of the components was determined by numerical simulations in order to focus the behaviour on the connections under normal and shear dominated loading. The chosen components were tested under static and dynamic loading conditions in a 3-point bending setup. Different displacement measurement techniques were applied to reveal the specimens behaviour, including digital image correlation.Test results were applied to validate idealized numerical models of adhesive and self-piercing riveting connections.
