Fatigue & Life Time Prediction

In the area of Fatigue & Life Time Prediction research is being carried out for the following subjects: experimental characterization and modeling of the fatigue behavior of fiber reinforced polymers, the identification of input parameters for the fatigue life analysis (i.e. fatigue strength, decrease of residual strength, stiffness degradation) and the generation of linear and non-linear models; the layer-based fatigue life analysis of polymer composites on the basis of the classical laminate theory (analytically describable stress conditions) and by using the finite element method (complex geometry thinwalled and moderately curved structures) as well as the experimental fatigue life testing under environmental conditions.
