riveted–adhesive hybrid joining technique is suitable for joining dissimilar material due to excellent performance and tightness of the joint. In this paper, electromagnetic self-piecing riveted–adhesive hybrid joining method was proposed to join Al/steel structure. The mechanical properties and failure behavior of electromagnetic self-piecing riveting, adhesive and its hybrid joints were compared. The shear tests were conducted, and digital image correlation (DIC) technique was employed to analyze the strain of the sheets. The typical failure fracture was observed to reveal the failure mechanism. The results showed that the peak load of the hybrid joint was 177.3% larger than that of the riveted joint, and the energy absorption of the hybrid joint was 360.0% and 47.9% higher than that of the riveted and bonded joint respectively. The failure process of electromagnetic self-piecing riveted–bonded hybrid joint could be divided into two parts: adhesive failure firstly and then rivet failure. The rivet in hybrid joint after adhesive failure could still suffer a certain amount of load, so that suddenly complete failure was not easy to happen. This indicated that the hybrid joint had better reliability and security. In general, the combination of electromagnetic self-piecing riveting and adhesive bonding could produce beneficial coupling effect.

铆接-粘合剂混合连接技术由于其卓越的性能和紧密性而适合于连接异种材料。本文提出了一种电磁自冲铆钉-胶粘混合连接方法来连接铝/钢结构。比较了电磁自冲铆钉，胶粘剂及其混合接头的力学性能和破坏行为。进行了剪切测试，并采用了数字图像相关（DIC）技术来分析片材的应变。观察到典型的破坏性断裂，揭示了破坏机理。结果表明，混合接头的峰值载荷比铆接接头的峰值载荷高177.3％，混合接头的能量吸收比铆接接头和粘结接头的峰值吸收分别高360.0％和47.9％。电磁自冲铆接混合接头的失效过程可分为两部分：首先是粘合失效，然后是铆钉失效。粘合失效后混合接头中的铆钉仍会承受一定的载荷，因此突然不完全失效是不容易发生的。这表明混合接头具有更好的可靠性和安全性。通常，电磁自冲铆接和胶粘结合可以产生有益的耦合效果。这表明混合接头具有更好的可靠性和安全性。通常，电磁自冲铆接和胶粘结合可以产生有益的耦合效果。这表明混合接头具有更好的可靠性和安全性。通常，电磁自冲铆接和胶粘结合可以产生有益的耦合效果。
