Abstract

Diplomsko delo opisuje postopek kalibracije materialnega modela za toplotno vplivana območja. Toplotno vplivana območja nastanejo v procesu MIG varjenja preizkušancev, ki so narejeni iz aluminijeve zlitine. Na začetku je predstavljeno teoretično ozadje aluminijevih zlitin in obnašanje materiala pri duktilnem lomu. Kalibracija materialnega modela je potekala z uporabo numeričnih simulacij na osnovi metode končnih elementov. V diplomskem delu je predstavljen uporabljeni model za opis duktilne poškodbe v Abaqusu. Rezultati numeričnih simulacij so validirani glede na rezultate nateznega preizkusa. Na podlagi rezultatov numeričnih simulacij sta določeni končni vrednosti kriterija začetka in napredovanja duktilne poškodbe.

Secondary title: Calibration and validation of a material model for heat affected zones of aluminium specimens
Secondary abstract: The bachelor thesis describes a material model calibration procedure for heat affected zones. Heat affected zones are formed during MIG welding of specimens, which are made of aluminium alloy. In the beginning, theoretical background of aluminium alloys and material behaviour under ductile fracture are presented. Material model calibration was performed using numerical simulations based on the finite element method. In the bachelor thesis the model used for predicting ductile damage in Abaqus is presented. Numerical simulation results are validated with uniaxial tension test results. Based on numerical simulation results, final values of the damage initiation criterion and damage evolution are defined.
