• Local-strain-approach
• sharp notched
• high mean stress
• cyclic stress relaxation

In this paper a concept is introduced, which can be used for the assessment of sharply notched components under high mean stress. The concept is based on the local strain approach. The extension of the concept is basically the consideration of the stress relaxation in the notch root. The concept is explained on a screw nut connection which is a very good example for a cyclically loaded component. The transition to the nominal stress approach, which is generally used for screw-nut connections, is done by using the example of a combined bending and axial loaded screw-nut connection.
