20.500.12556/RUL-171417 Analiza križnega preizkušanca za materialno testiranje in karakterizacijo MT 2.0 Analysis of a cruciform test specimen for material testing and characterization MT 2.0 V magistrski nalogi so bile obravnavane omejitve metodologije materialnega testiranja 2.0 (MT2.0), ki temelji na DIC in VFM. Za trgalni stroj za materialno karakterizacijo je bila predlagana merilna celica 10 kN. Z virtualnim eksperimentom v okoljih ABAQUS/Standard in MatchID ter realnim naključnim vzorcem je bil analiziran vpliv geometrije, šuma in korelacije na natančnost rezultatov. Validacija je potrdila zanesljivost križnega preizkusa. Ugotovljena je bila ustreznost 2D DIC tehnike, oblikovane pa so bile tudi smernice za izbiro optimalnih nastavitev korelacije. The master's thesis addressed the limitations of the material testing 2.0 (MT2.0) methodology, which is based on DIC and VFM. A 10 kN load cell was proposed for the testing machine used in material characterization. Using a virtual experiment in ABAQUS/Standard and MatchID environments with a real random speckle pattern, the influence of specimen geometry, image noise, and correlation on the accuracy of the results was analyzed. Validation confirmed the reliability of the cruciform specimen. The adequacy of the 2D DIC technique was established, and guidelines for selecting optimal correlation settings were developed. materialno testiranje MT 2.0 korelacija digitalnih slik (DIC) anizotropija metoda virtualnih polj (VFM) križni preizkušanec ravninsko napetostno stanje (RNS) material testing MT 2.0 digital image correlation (DIC) anisotropy virtual fields method (VFM) cruciform test specimen plane stress state true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-08-26 08:30:47 2025-08-26 08:30:50 2025-09-01 03:48:05 0000-00-00 00:00:00 2025 0 0 XXII, 73 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.1:531.7:004.942(043.2) 274717 246924547 42959.pdf 42959.pdf 1 F8F4A38240C6570D70DE754A424274F0 76d947c319c6bfdbf513cbdb5541d63f8bbc8b3e77456746485c4fae36fcfca3 16066886-8246-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=214731 Fakulteta za strojništvo 0 0 0
