Micromechanical fatigue lifetime predictions, in particular for the high cycle fatigue regime, require an appropriate modelling of mean stress effects in order to account for lifetime reducing positive mean stresses. Focus of this micromechanical stu

Der Zensus 2011 war zur Entlastung der Auskunftspflichtigen und zur Reduzierung der Kosten ein registergestützter Zensus, bei dem im Gegensatz zu früheren Volkszählungen nicht alle Personen und Haushalte befragt wurden. Der Zensus 2011 hat dabei u

Martensitic high-strength steels are prone to exhibit premature fatigue failure due to fatigue crack nucleation at non-metallic inclusions and other microstructural defects. This study investigates the fatigue crack nucleation behavior of the martens

A fundamental prerequisite for the micromechanical simulation of fatigue is the appropriate modelling of the effective cyclic properties of the considered material. Therefore, kinematic hardening formulations on the slip system level are of crucial i

The last censuses in Germany were accomplished in 1987 (former federal states) and 1981 (new federal states), respectively. Germany was the only country which did not participate in the EU-wide census in 2000. A traditional census was not feasible on

The propagation of planetary waves at the 500 mb level is investigated by applying an extended version of wavenumber-frequency analysis. By separating the variance attributable to wave disturbances from the total variance, one may account for the noi
