Kurzbeschreibung (Abstract)
The fatigue behavior of the austenitic stainless steel X6CrNiNb18-10 (1.4550, AISI 347) is investigated. Experimental data are generated at room temperature, at elevated temperatures and further under thermo-mechanical conditions. Research is focused on generating data for parameter identification, especially for the improvement of material models. The influence of temperature on the stress-strain behavior and the fatigue life is presented. Finite element simulations are used to describe fatigue crack growth under thermo-cyclic loading conditions. Using the example of a thick-walled tube, the essential parameter for the crack growth rate—the effective cyclic J-integral—is determined for eight temperature transients (defined by fluid temperature, heat transfer coefficient and inner pressure). An approximation of the effective cyclic J-integral allows modeling without consideration of the crack geometry in the model.
