Projects of the Second Period

In the first funding period of the priority programme, damage mechanisms in the fatigue process were investigated experimentally, taking into account defined influences, described using damage indicators and modelled using various approaches, initially for a few load cycles.

In the second funding period of the priority programme, the focus of the work is on determining supplementary findings on the mechanisms of fatigue damage, further developing the models and linking them to the Experimental Virtual Lab with the aim of predicting degradation. Among other things, the influence of more complex stress time courses in terms of operational loads on the damage mechanisms is to be investigated and evaluated with regard to damage accumulation. In addition to the cross-scale modelling of the geometry, innovative multi-scale methods of the temporal course are also to be considered in particular, which enable the modelling of high numbers of load cycles in limited simulation time.
