This paper presents the work on the development of a dimensioning concept for punctual joined sheet metal structures shown for the example of clinched joints. The precondition for finite-element calculations is the knowledge of experimental data such as strength and stiffness parameters under quasistatic and dynamic loads. An innovative method for the identification of these parameters under multiaxial load directions at a single punctual joint element, developed at the LWF, uses the double cup specimen (DC-Specimen). A so called FE joint model for punctual joining elements allows the simulation of the mechanical behaviour of a joint. It is derived from experimental testing results. This model gives the ability to calculate the loads at the joint with the finite-element method and presents a base for the stiffness analysis and durability calculation.
