| Abstract Scope |
The paper presents a new joining process for mixed joints of different metals and joints of metallic and non-metallic materials. The joining process is based on self-piercing rivet elements that penetrate the joining partners and produce an interlock between the parts due to their geometry. In contrast to conventional self-piercing processes such as self-pierce riveting with semi-tubular rivets (SPR), the new process does not require a specially shaped die as a counter tool. This paper presents the development of a suitable rivet geometry that on the one hand provides sufficient stability when piercing the parts. On the other hand, flaring of the rivet element must be achieved in order to form the joint. Two different types of rivets are investigated to cover a wider range of materials and thicknesses of the parts to be joined.The development of the rivet geometry is based on FEM analyses with SFTC Deform-3D.The challenges and solution approaches are presented regarding the modeling of material damage and separation in the three-dimensional model of the riveting process. The consideration of macro-mechanical and geometrical criteria for element deletion is of particular importance in order to obtain stable models with good results.The applied model was validated based on comparisons with experimental results. Possibilities and limitations of the process simulation of the new joining process are discussed. |
