| Abstract Scope |
In the framework of a numerical fatigue approach the cyclic material properties have to be known. Therefore, stress- and strain-controlled fatigue tests have to be performed in order to derive the material properties in order to describe appropriate the cyclic structure behavior under service loading conditions. With respect to the typical component sizes and built times, small scale specimens are preferred, providing that the specimens behavior can be transferred to the components.
Considering that, methods to transfer the specimens behavior to components are required. This transfer function have to manage effects related to the different sizes of specimens and component and stress-strain development caused by the loading conditions and history.
At the end, a modified fatigue approach concept, which takes into account the main influences on the fatigue and fulfills the industrial requirements of optimized ratio of computation time and validity of the fatigue approach, will be derived. |
