Review the recorded symposium!
Nowadays simulation of the fatigue life is an essential part of the development of components in the automotive and machinery industry.
A lot of parameters influence the fatigue life as the local stress, temperature etc. Notches have the strongest impact on fatigue life due to an increase of the local stress. Also, the local fatigue strength is increased because of a support effect from the neighboring areas, where the stress is already reduced.
To account for this effect, several methods exist, each with their specific advantages and disadvantages. In this contribution an overview is given with brief descriptions for some common methods like the stress gradient concept, volume concept, the concept of the critical distance and the concept of effective stresses. The methods are compared both from a theoretical and practical point of view.
