Abstract

Zaključna naloga obravnava vpliv poroznosti na življenjsko dobo delov iz aluminija. V nalogi kot material, ki ga preučujemo, uporabimo AlSi7Cu0.5Mg-T6. V prvem delu naloge pregledamo Murakami in El Haddad model določitev trajne dinamične trdnosti, ki ju uporabimo v numerični analizi. Nato pregledamo rezultate fizičnega Wöhlerjevega testa. V drugem delu naloge izvedemo simulacijo preizkusa dinamične trdnosti z uporabo lokalnih materialnih lastnosti in preizkušancu določimo Wöhlerjevo krivuljo. Ugotoviti želimo vpliv lokalnih materialnih lastnosti in primerjati ustreznost modela določitve trajne dinamične trdnosti.

Secondary title:	Porosity effect on fatigue life of aluminium parts
Secondary abstract:	In this thesis, the influence of the porosity on the fatigue life of aluminum parts is analyzed. AlSi7Cu0.5Mg-T6 is used as the studying material in the paper. In the first part, the Murakami and El Haddad model are reviewed. Then, the results of the physical Wöhler test are examined. In the second part of the task, a simulation of fatigue life using local material properties is performed and the Wöhler curve is determined from it. The influence of local material properties is determined and the suitability of the models for determining fatigue life is analyzed.
