Robust joining point design for semi-tubular self-piercing rivets

This paper describes an approach for robust design of a mechanical joining process, semi-tubular self-piercing riveting, in real time. Using joining process simulations as a basis, a metamodel is constructed for this purpose, which is subsequently used to optimize the robustness. In this way, joining points can be designed so that there are no impermissible effects on the result quantities in terms of specified scatter input variables.
