Abstract—The society demand for a responsible interaction with the environment and resources has increased over the last decades. Therefore, lightweight design has been the focus in research and development for several years. There are different strategies for obtaining the aims of weight reduction and efficient material usage. New lightweight materials and designs underlie a difficult economic introduction in existing manufacturing processes and products. This paper introduces the design for a new connection element. The collar-connection element is based on the collar forming process. It consists of two collars having different diameters fitting into each other. A mechanical joint connects both collars and provides a load-transmission between the sheet metals. Hereby, the collar-connection element enables the design of an all-metal-sandwich structure possessing a high specific stiffness and strength. This paper presents the functionality of the collar-connection element and investigates the acting joint mechanisms.
Index Terms—Collar forming, connection element, joining mechanism, joining by forming.
