PREGLED I SISTEMATIZACIJA NAJČEŠĆE KORIŠTENIH MATEMATIČKIH MODELA ZA OPISIVANJE KRIVULJE NAPREZANJA PLASTIČNOG TEČENJA MATERIJALA
In this bachelor thesis provides a theoretical overview and review of the most commonly used mathematical models for describing the stress-strain curves of flow stress of materials, and the importance of their application in practice when selecting the parameters of technological processes of metal forming. Given the most common mathematical models, it is shown why they as such are not fully reliable because they do not take into account all the influential parameters. Based on this, a new mathematical model is presented that is much more complicated than the most commonly used ones, which as such takes as many influential parameters as possible. For the given mathematical models, the curves they describe are shown. Based on the bachelor thesis, the conclusion of the given topic is finally given.
