Termomekanisk utmattning av Sanicro 25 : Materialmodellering med finita elementmetoden / Thermomechanical fatigue of Sanicro 25 : Material modeling using the finite element method

Karjalainen, Marcus, Klarholm, David January 2014 (has links)
The report aims to describe the austenitic stainless steel Sanicro 25 from a thermomechanical point of view. The thermal and mechanical properties of the material make it suitable for use in coal – and thermal power plants. By the use of Sanicro 25 it would be possible to bring the efficiency of these plants up while bringing the carbon emissions down.A material model is created from material testing and validated through simulation in the finite element software Abaqus. The model that has been derived describes the material behavior during loading and stress relaxation for the first cycle in a thermomechanical fatigue test well. The unloading part of the cycle however cannot be described correctly by the use of this model. / Rostfritt
