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.

提出了一种新颖的测试装置，用于验证承受静态和冲击载荷的钢和铝部件之间的混合连接器模型。提议的组件包括两个由钢和铝制成的帽子型材，通过粘合剂结合自冲铆接连接在一起。组件的几何形状由数值模拟确定，以便将行为集中在法向和剪切主导载荷下的连接上。所选组件在静态和动态负载条件下以 3 点弯曲设置进行测试。应用不同的位移测量技术来揭示试样行为，包括数字图像相关性。测试结果用于验证粘合剂和自冲铆接连接的理想化数值模型。
