Kurzbeschreibung (Abstract)
In this paper two different kinds of notch approximation methods are presented. The proposed methods are known as the incremental notch approximation method (e. g. Neuber method 1 or ESED 2, 3) and the structural yield surface approach (SFF) (after Köttgen et al. 3), while two different approaches of the SFF are used. All methods are capable to handle multiaxial cyclic loading. For a validation, the methods are compared to the results of a finite element analysis (FEA) of a notched component. The presented comparison is made for a non-proportional loading case. One objective of the work is to find out, which is suitable to extend it to thermomechanical loads as a next step.
