20.500.12556/RUL-185904 Vrednotenje reoloških modelov za simulacijo odziva hiperelastičnih materialov Evaluation of rheological models for simulating the response of hyperelastic materials V okviru diplomskega dela smo z uporabo metode končnih elementov in programske opreme Abaqus ovrednotili delovanje obstoječih reoloških modelov za simulacijo odziva hiperelastičnih materialov. Te materiale smo podvrgli različnim obremenitvenim stanjem, kot so lezenje, ciklične obremenitve in relaksacija ter spremljali njihov odziv. Naredili smo tudi konvergenčno analizo. Hiperelastične materiale smo definirali z Neo-Hookovim zakonom in Ogdenovim modelom. Ugotovili smo, da Neo-Hookov model omogoča zadovoljiv opis materiala pri manjših deformacijah, medtem ko se pri večjih deformacijah kot primernejši izkaže Ogdenov model, saj boljše popiše obnašanje hiperelastičnih materialov. Eksperimentalne podatke in numerične analize smo med seboj primerjali in ugotavljali ujemanja ter razlike na podlagi pridobljenih rezultatov. As part of our thesis, we used the finite element method and Abaqus software to evaluate the performance of existing rheological models for simulating the response of hyperelastic materials. We subjected these materials to various loading states, such as creep, cyclic loading and relaxation, and monitored their response. We also performed a convergence analysis. Hyperelastic materials were defined using the Neo-Hook's law and the Ogden model. We found that the Neo-Hook's model provides a satisfactory description of the material at smaller deformations, while the Ogden model is more suitable for larger deformations, as it better describes the behavior of hyperelastic materials. We compared experimental data and numerical analyses and identified similarities and differences based on the results obtained. gumijasti materiali hiperelastični materiali reološki modeli Neo-Hookov zakon Ogdenov hiperelastični model relaksacija ciklična obremenitev lezenje mehanika rubber materials hyperelastic materials rheological models Neo-Hookean law Ogden hyperelastic model stress relaxation cyclic loading creep mechanics true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-08-22 08:31:41 2026-08-22 08:31:43 2026-08-23 04:09:50 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 288195 48581.pdf 48581.pdf 1 4EF2641A70DD6605F08CAB53E24504C0 8c26156d06c79257e5ea270217007c56cca4d4fa40a667669c6a41654fdfcc20 bf057ffa-9df2-11f1-9b0d-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=244911 Fakulteta za strojništvo 0 0 0
