Abstract

Namen diplomskega dela je dokumentirati potek uporabe programa za validacijo materialnih in poškodbenih modelov za implementacijo le-teh pri numeričnih simulacijah termo-mehanskega utrujanja aluminijevih zlitin. Predstavljeno je teoretično ozadje utrujanja materiala, v katerega uvrščamo velikociklično, malociklično in termo-mehansko utrujanje materiala. Prav tako sta predstavljena viskoplastični materialni model in poškodbeni model, ki sta ključ za izračun končnega števila ciklov. Podane so osnovne mehanske in termične lastnosti ene izmed obravnavanih aluminijevih zlitin. Opisan je postopek pregleda rezultatov eksperimentalnih testov termo-mehanskega utrujanja aluminijevih zlitin, ki so bili izvedeni pri temperaturah do 320 °C. V zaključku diplomskega dela je predstavljen postopek uporabe programa AVL TMF TOOLBOX in skriptov, ki obdelajo in izpišejo podatke, ki so pomembni za validacijo materialnega in poškodbenega modela.

Secondary title: Validation of material and damage models for numerical simulations of thermo-mechanical fatigue
Secondary abstract: The main purpose of this diploma thesis is to document the course of using the damage model validation program for its implementation in numerical thermo-mechanical fatigue simulations of aluminum alloys. The theoretical background of metal fatigue is separately presented for the high cycle fatigue, low cycle fatigue and thermo-mechanical fatigue. In addition, the viscoplastic material and damage model are presented, which are the main key for Nf calculations. Basic thermo-mechanical properties of aluminum alloy are given. The review results procedure, of the raw thermo-mechanical fatigue experiments data are presented, which were carried out in a temperature region up to 320 °C. The conclusion of the thesis consists of the method of using the AVL TMF TOOLBOX program.
