摘要

摘要: 在钢铝压印连接界面之间加入胶粘剂，能有效提高接头性能，但接头的力学行为与失效机理非常复杂。以双相高强钢板DP590和铝合金板6061-T6为连接材料，对钢铝压-胶复合连接接头的力学行为和失效机理进行了有限元模拟和试验研究。基于ABAQUS有限元分析软件，采用GTN(Gurson tvergaard needleman)模型+内聚力(Cohesive zone)模型的混合失效模型，模拟了压-胶复合连接接头的成形和失效行为。通过压印连接、胶接以及压-胶复合连接接头的搭接剪切试验，对比分析了以上3种接头的失效模式和力学行为。结合压-胶复合连接接头的胶粘剂分布规律和胶层失效过程，揭示了压-胶复合连接接头的失效机理。

Abstract: Inserting adhesive in the steel-aluminum clinched joint can improve the joint performance. The mechanical behavior and failure mechanism of the joint are very complicated. In this paper, the steel-aluminum clinch-bonded hybrid joint of the dual-phase high-strength steel DP590 and aluminum alloy 6061-T6 was manufactured. And the mechanical behavior and failure mechanism were studied with the simulation and experimental methods. Based on ABAQUS finite element analysis software, the mixed failure model for GTN (Gurson tvergaard needleman) + cohesive zone (CZ) was used to simulate the forming and failure process of the clinch-bonded hybrid joint. Through the shear test of the clinched, bonded and clinch-bonded joints, the failure mode and mechanical behavior of the three joints were analyzed. Combining with the adhesive distribution and the failure process of the adhesive layer, the failure mechanism of the hybrid joint was revealed.
