Joining by compression of metallic inserts has been recently developed by the authors to create invisible lap joints between metal and polymer laminates. This paper revisits the process with the objective of proposing a new type of bi-material (polymer–metal) cylindrical insert for lightweight construction applications that is capable of ensuring complete filling of the joint at the end of stroke without increasing the forming force and the risk of sheet bending. The presentation is built upon a combined experimental and finite element research work focused on the modes of deformation, formability limits, forming forces, and resistance strength that lap joints produced with the new bi-material cylindrical inserts are able to withstand before failing. Results allowed designing a simple and easy to fabricate bi-material cylindrical insert that overcomes the main problems that have been pointed out to the metallic inserts earlier proposed by the authors.

作者最近开发了通过压缩金属嵌件进行连接以在金属和聚合物层压板之间创建不可见的搭接接头。本文以提出一种用于轻型建筑应用的新型双材料（聚合物-金属）圆柱形插入物为目标，对这种过程进行了重新研究，该插入物能够确保在冲程结束时完全填充接头，而不会增加成形力和切削力。板材弯曲的风险。该介绍建立在结合实验和有限元研究工作的基础上，研究工作集中于变形模式，可成形性极限，成型力和抵抗强度，而新的双材料圆柱形刀片生产的搭接接头在失效之前能够承受。
