20.500.12556/RUL-147114 Vrednotenje nastanka poškodbe v fotopolimernem gradivu pri statični in ciklični obremenitvi Evaluation of damage formation in photopolymer material under static and cyclic loading Magistrska naloga obravnava identifikacijo nastanka poškodbe v fotopolimernem gradivu. Z napredovanjem dodajalnih tehnologij je 3D tiskanje postala splošno uporabljena in dostopna tehnologija izdelave prototipov in funkcionalnih delov. Obravnavani material se uporablja pri 3D tiskanju z obrnjeno stereolitografijo z uporabo LCD zaslona in UV svetilk. Pridobivanje informacij za vrednotenje nastanka poškodbe smo izvedli z nateznimi, tlačnimi in cikličnimi preizkusi, iz katerih smo pridobili informacije o deformacij in napetosti ter posledično materialne lastnosti. Poleg tega smo preizkušance snemali s hitro tekočo kamero. Posnetke smo vizualno in s pomočjo digitalne korelacije slik analizirali s ciljem ugotovitve vzroka in dinamike nastanka poškodbe. Pridobljene rezultate smo primerjali z numerično analizo. In this master thesis we deal with identification of damage formation in photopolymer material. With advancing of additive technologies, 3D printing has become widely used and accessible technology for prototyping and functional parts. The material under consideration is used in 3D printing with inverted stereolithography using an LCD screen and UV lamps. The data about stress and deformation needed for evaluating the damage formation were obtained from tensile, compresive and cyclic tests. The specimens were also filmed with high speed camera during the tests. Recordings were analyzed visually and with the help of digital image corelation for the purpose of determining the used to determine the cause and dynamics of damage formation. The obtained results were compared with numerical analysis. dodajalne tehnologije fotopolimer preizkusi hitro tekoča kamera materialne lastnosti nastanek poškodbe digitalna korelacija slik numerična analiza additive manufacturing photopolymer experiments high speed camera damage formation digital image correlation numerical analysis true false false [V.
