SUMMARY:Joining of high strength steels in applications requiring a high number of load cycles 
DESCRIPTION:One essential criterion for the design of joints in many applications is the fatigue behaviour with a coincident focus on lightweight design. In this case an increase of load cycles by the use of high strength steels in combination with welding is limited.
Experiences from sectors like automotive engineering show, that bonded joints exhibit excellent behaviour under cyclic loads. Nevertheless, there is only a low use of adhesive bonding in sectors like agricultural engineering, commercial vehicles or plant engineering. One important reason for that is mainly a lack of regulations and standards, as they already exist for the design of welded joints. Typical standards used are for example IIW-guidelines, the Eurocode or the FKM-guideline. They allow the determination of Woehler curves for welded joints, while a design method for adhesive joints is not included. In addition to that, the boundary conditions in these sectors are different to those seen in automotive engineering. They can be characterized by a lot of small and medium sized companies using a large proportion of manual manufacturing methods. Further differences arise from the wall thickness of the steel sheets used, tolerances and the corrosive conditions caused by the respective environment. 
In order to fill this gap, a design method for load-bearing adhesive joints in applications using thicker steel sheets was developed according to the FKM-guideline. The method is based on only few input variables to create a Woehler curve and to estimate the operational stability of an adhesive joint as it can be used in the sectors mentioned.
