20.500.12556/RUL-171622 Zasnova 3D tiskanih struktur z oblikovnim spominom iz PLA materiala Design of 3D printed shape memory structures made of PLA material V diplomskem delu je predstavljen razvoj strukture z oblikovnim spominom v obliki satovja z namenom balistične zaščite. Glavni cilj je izoblikovati strukturo, ki se bo po obremenitvi, kot je udarna obremenitev ali tlačno testiranje, deformirala in nato zaradi spremembe temperature povrnila v prvotno stanje ter ponovno služila svoji uporabi. V teoretičnem delu so opisani značilna oblika satovja, lastnosti materiala PLA in mehanske lastnosti glede na smer dodajanja materiala pri izdelavi strukture ter vrste obremenitve, s katerimi smo preizkušali naše vzorce. V praktičnem delu so opisani postopek razvoja strukture od začetne skice do končnega modela, izdelava vzorcev z aditivno tehnologijo, simulacije v programskem okolju Abaqus ter na koncu še realni preizkusi in analiza rezultatov, kjer smo opazovali, kako se struktura dejansko obnaša med obremenitvijo in koliko se ta povrne v prvotno stanje. The thesis presents the development of a shape-memory structure in honeycomb form for ballistic protection purposes. The main objective was to design a structure that undergoes deformation under load, such as impact or compression testing, and returns to its original shape due to temperature-induced recovery, thus allowing it to be reused. The theoretical part of the thesis describes the typical honeycomb shape and the properties of PLA material. The mechanical properties depend on the element’s printing orientation and the types of loads applied during sample testing. The practical part outlines the complete development process of the structure, from the initial sketch to the final model, including additive manufacturing of the samples, simulations in the Abaqus software, and finally, real-life testing and analysis. The results reveal how the structure behaves under compressive loading and the extent to which it recovers its original shape. celična struktura numerične simulacije kompozit balistična zaščita pnevmatski top cellular structure numerical simulations composite ballistic protection pneumatic cannon true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-08-29 08:31:29 2025-08-29 08:31:32 2025-09-10 03:33:15 0000-00-00 00:00:00 2025 0 0 XX, 45 str. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.172.254:678:004.925.84(043.2) 274973 247244035 43042.pdf 43042.pdf 1 DCF7437B168AF63517EDC334A95C3059 8d06f0182fdc9fa48f0381af5a976bf2781d6a5e9e742691361e81a579909e7b ac3600dc-84a1-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=215002 Fakulteta za strojništvo 0 0 0
