Abstract

Definiranjem postupka, rezultata i opreme korištene u domeni računalne tomografije (eng. Computed Tomography - CT), postavljen je temelj predložene nerazorne metode za karakterizaciju ponašanja materijala uslijed mehaničkog opterećenja. Predstavljen je korišteni ispitni uzorak te su opisani uvjeti i parametri cikličkog mehaničkog ispitivanja. Postepeno su definirani svi koraci nužni za primjenu metode korelacije digitalnih volumena (eng. Digital Volume Correlation – DVC), uz navođenje grešaka, njihovih uzroka i mogućih korekcija. Predložena metoda predstavljena je uz matematičku potkrjepu, te su navedeni svi programski paketi vezani za njenu primjenu. Prikazani su svi relevantni rezultati DVC analize. Jednako tako, kao vremenski i računalno manje zahtjevna metoda korelacije, definirana je i korelacija digitalnih volumena temeljena na 2D projekcijama (eng. Projection-based Digital Volume Correlation – P-DVC) te su prikazani njome dobiveni rezultati.

Abstract (english)

By defining the method, results and equipment used in the domain of computed tomography (CT), the basis for a proposed non-destructive method, used to characterize the behavior of materials under mechanical loading, is set. The utilized test sample is showcased and the conditions and parameters of the cyclic mechanical testing process are described. All steps necessary for the application of the Digital Volume Correlation (DVC) method are gradually defined, including the descrpition of errors, their causes and possible corrections. The proposed method is showcased with mathematical support, and all the software packages related to its application are listed. All of the relevant DVC analysis results are presented. Similarly, as a both, time-wise and computationally less demanding correlation method, a 2D Projectionbased Digital Volume Correlation (P-DVC) is defined and the results obtained through its application are presented.
