20.500.12556/RUL-175325 Pristopi modeliranja mehanskega odziva kompozitnih struktur z uporabo metode končnih elementov Techniques for modelling of mechanical response of composite structures using finite element method V nalogi smo primerjali numerične pristope modeliranja kompozitnih struktur. Preizkusili smo 2D lupinske, 3D lupinske in kombinirane elemente ter jih ovrednotili z nateznimi in upogibnimi preizkusi. Pokazalo se je, da kombinacija 2D in 3D lupinskih elementov najbolje ustreza eksperimentalnim rezultatom, saj posamezni pristopi togost bodisi precenijo bodisi podcenijo. Predlagani model omogoča zanesljivejšo napoved mehanskega odziva že v fazi načrtovanja. This thesis compares numerical approaches to modelling composite structures. 2D shell, 3D shell, and combined elements were tested and validated against the tensile and bending experiments. The results indicate that the combination of 2D and 3D shell elements achieves the closest agreement with experimental findings, whereas the individual approaches tend to either overestimate or underestimate stiffness. The proposed combined model therefore provides a more reliable prediction of the mechanical response already in the design phase. kompoziti numerično modeliranje metoda končnih elementov 2D in 3D lupinski elementi eksperimentalno ovrednotenje composites numerical modelling finite element method 2D and 3D shell elements experimental validation true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2025-10-24 08:31:01 2025-10-24 08:31:03 2025-12-10 03:35:39 0000-00-00 00:00:00 2025 0 0 XX, 78 str., [2] f. pril. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.31:678.061:519.61(043.2) 277328 255641603 45518.pdf 45518.pdf 1 E1A6B016CDD25FCE183DE8E81FB0C33E 3bea365a3e6a5ccdcc2deb4b13ab415e06809e1f1aafa501ccdea39977032b61 b9a46183-b0a2-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=220773 Fakulteta za strojništvo 0 0 0
