Raziskovanje pojava cikličnega lezenja pri aluminijevi zlitini

Stražišar, Matija (author), Nagode, Marko (mentor), Šeruga, Domen (co-mentor)

Zaključna naloga raziskuje pojav cikličnega lezenja v izbrani aluminijevi zlitini, pri čemer nas je predvsem zanimalo nazadujoče oz. napredujoče ciklično lezenje. Naloga zajema pregled literature na področju lezenja in način izvedbe preizkusov, pri čemer se osredotoča na to, kako preizkuse izvesti glede na omejitve preizkuševališča in kako rešiti s tem povezane probleme, ki lahko nastanejo. Naloga obravnava tudi interpretacijo in primerjavo rezultatov, ki jih je zajel trgalni stroj napram tem, ki jih je zajel video ekstenziometer.

• Title: Investigation of the phenomenon of cyclic creep in the aluminium alloy

Abstract

The final thesis investigates the phenomenon of cyclic creep in a selected aluminium alloy, where we were mainly interested in the shakedown or ratcheting. The thesis includes a review of the literature on creep and how to perform the tests, focusing on how to perform the tests given the constraints of the test system and how to solve the associated problems that may arise. The thesis also deals with the interpretation and comparison of the results captured by the testing system versus those captured by the video extensiometer.
