Abstract:

Artikkelissa tarkastellaan metallien korkealämpötilan virumismurron ja virumisväsymisen mallintamista. Aluksi esitetaan lyhyt katsaus virumisen fysikaalisiin perusteisiin ja virumismalleihin.  Kaytetyn termodynaamisesti konsistentin materiaalimallin konstitutiiviset yhtälöt esitetaan varsin perusteellisesti. Mallin materiaaliparametrit määritetään 7CrMoVTiB10-10 teräkselle lampötila-alueella 500 - 600 C. Malli on implementoitu ANSYS elementtimenetelmäohjelmiston USERMAT-aliohjelmaksi.
