  • Numerical methods for TMF cycle modeling
    Zaletelj, Henrik ; Fajdiga, Gorazd ; Nagode, Marko
    Experimental tests for the endurance evaluation of the machine parts that are exposed to thermomechanical fatigue (TMF) require advanced and expensive testing machines. Numerical methods for the ... determination of stress-strain material behavior have become very frequent and known due to lower costs. There are several different approaches for the determination of stress-strain behavior. In the article three different numerical methods and their results are presented. The numerical results for different load conditions are compared with the experimental results and the accuracy of the methods can be compared. The Chaboche, Skelton and Prandtl operator approaches are presented, presuming a stabilized elastoplastic response and not including creep. The properties of the model, their weaknesses and possible improvements are also studied in the paper.
