Abstract

Cilj dela je pregledati in primerjati najpogostejše metode za inverzno identifikacijo materialnih parametrov. Najprej je narejen teoretičen pregled, nato pa je izvedena verifikacija in primerjava na analizi realnega štiri točkovnega upogibnega preizkusa dveh izmed naštetih metod - metode posodabljanja modela končnih elementov in metode virtualnih polj. Na koncu smo primerjali konvergenco metode in njihovo stabilnost ter opisali nastale težave pri analizi. Izvedena je bila tudi kratka statistična primerjava rezultatov.

Secondary title: Identification of orthotropic elastic material parameters based on flexural test
Secondary abstract: The main subject of this master%s thesis is the overview and comparison of the most common methods od inverse identification of material parameters. The methods observed and examined in the master%s thesis are primarily overviewed in order to choose the two that are later on the main focus of the thesis. These two methods % Finite Element Model Updating Method and Virtual Fields Method % are verified and compared based on the examination of an actual four-point flexural test. Based on the test, the thesis observes and compares the convergence and stability of the methods and tries to describe adn eliminate the difficulties that appeared during the design of the analysis. The results achieved are briefly statistically compared in the ending of the thesis.
