Abstract This study investigates the single-strap joints (adhesively bonded spot-welded) under static loading. Experimental tensile tests are carried out to validate the numerical analyses. For this purpose, the specimens of dissimilar materials were prepared by joining them with a thin layer of a two-component epoxy-based adhesive at one side and spot welding at the other side. Then, they were tested under tensile-loading conditions. The numerical analyses were performed according to the cohesive zone model (CZM) to estimate the failure loads of the joints. The failure loades of the joints with different dimensions were studied to evaluate the conditions causing the cohesive failure of either the adhesive layer or the weld nugget. It is shown that with minor changes in the bondline and weld designs, the joining process of the dissimilar materials will be more feasible.

通过粘合点焊接头粘合不同材料：内聚区模型技术

摘要 本研究研究了静载荷下的单条带接头（胶粘点焊）。进行实验拉伸试验以验证数值分析。为此，不同材料的样品通过在一侧与两组分环氧基粘合剂的薄层连接并在另一侧进行点焊来制备。然后，它们在拉伸载荷条件下进行测试。根据内聚区模型（CZM）进行数值分析以估计接头的破坏载荷。研究了不同尺寸接头的破坏载荷，以评估导致粘合剂层或焊核内聚破坏的条件。结果表明，在粘合层和焊缝设计中稍有变化，
