20.500.12556/RUL-180519 Določitev protokola za eksperimentalno testiranje in materialno modeliranje mehanskega odziva vretenčne trabekularne kosti Development of an experimental protocol and material modeling of the compressive response of vertebral trabecular bone V delu obravnavamo tlačni odziv trabekularne kosti vretenc na podlagi napetostno–deformacijskih krivulj iz literature. Na osnovi pregleda literature smo opredelili standarden postopek tlačnega testiranja. Izbrali smo tri referenčne krivulje, jih digitalizirali in določili navidezni elastični modul, maksimalno napetost ter pripadajočo deformacijo. Odziv smo rekonstruirali z modelom Kolesnikov–Meltser in ujemanje ovrednotili z RMSE, NRMSE ter relativno napako pri lomu. Model se bolje ujema pred maksimumom, po maksimumu pa odstopanja narastejo. We investigate the compressive response of vertebral trabecular bone based on stress–strain curves reported in the literature. From the literature review, we defined a standard compression testing procedure. Three reference curves were selected, digitized, and used to determine the apparent elastic modulus, the maximum stress, and the corresponding strain. The response was reconstructed using the Kolesnikov–Meltser model, and the agreement was evaluated using RMSE, NRMSE, and the relative error at fracture. The model matches the data better before the peak, while deviations increase after the peak. vretenca trabekularne kosti tlačni preizkusi napetostno deformacijske krivulje digitalizacija podatkov materialno modeliranje numerične simulacije vertebrae trabecular bones compression tests stress–strain curves data digitization material modeling numerical simulations true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-03-11 08:30:55 2026-03-11 08:31:00 2026-03-12 04:44:38 0000-00-00 00:00:00 2026 0 0 XV, 38 f. 2026 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 620.173:616.71(043.2) 283305 271277059 46619.pdf 46619.pdf 1 58DE0B622B3D549E9E6ECA1F075EE51F e96c21252d901488b10249530ca7c98593fbd0e1b84c192f696a9c299920829a d3a0c036-1d1b-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=229969 Fakulteta za strojništvo 0 0 0
