Abstract

U ovom radu provedena su ispitivanja deformacijskih svojstava suvremenim metodama digitalne korelacije slike i termografije te mogućnost korištenja suvremene metode 3D optičkog mjerenja odnosno inspekcije upotrebom automatiziranog mjernog sustava Atos Scanbox na ispitnim uzorcima za statičko vlačno ispitivanje. Dimenzijska i geometrijska kontrola ispitnih uzoraka provedena je usporedbom skeniranog (stvarnog) ispitnog uzorka bakra i njegovog CAD modela. Na ispitnim uzorcima bakra i aluminij-magnezij legure provedeno je određivanje deformacijskih svojstava metodama digitalne korelacije slike i termografije tijekom statičkog vlačnog ispitivanja odnosno plastične deformacije. Utvrđena je mogućnost inspekcije dimenzija i geometrije ispitnih uzoraka 3D optičkim mjerenjima te određivanje i usporedba deformacijskih svojstava dobivenih metodama digitalne korelacije slike i termografije tijekom plastične deformacije bakra i aluminij-magnezij legure. Usporedbom rezultata mjerenja skeniranog ispitnog uzorka bakra i CAD modela utvrđeno je da ne postoje značajna dimenzijska i geometrijska odstupanja. Metodama digitalne korelacije slike i termografije utvrđene su razlike u deformacijskim svojstvima između bakra i aluminij-magnezijeve legure.

Abstract (english)

In this work, tests of deformation properties were carried out using the modern methods of digital image correlation and thermography, as well as the possibility of using modern method of 3D optical measurement, i.e. inspection using the automated measuring system Atos Scanbox on test samples for static tensile testing. The dimensional and geometric control of the test samples was performed by comparing the scanned (actual) test sample of copper and its CAD model. On the test samples of copper and aluminum-magnesium alloy, deformation properties were determined using the methods of digital image correlation and thermography during static tensile test, i.e. plastic deformation. The possibilities of dimensional and geometric inspection of the test samples with 3D optical measurements were determined. The determination and comparison of deformation properties, obtained by the digital image correlation and thermography, during the plastic deformation of copper and aluminum-magnesium alloy were determined. The comparison of the measurement results of the scanned copper test sample and the CAD model showed that there are no significant dimensional and geometric deviations. The differences in deformation properties between copper and aluminum-magnesium alloy were determined using the methods of digital image correlation and thermography.
