20.500.12556/RUL-164429 Mehanistični opis deformacije bakterijskih sten pod vplivom hidrostatičnega tlaka Mechanistic description of bacterial wall deformation under hydrostatic pressure V nalogi se bomo ukvarjali s popisom odziva sferocilindrične bakterije na vpliv hidrostatičnega tlaka. Na poenostavljenem modelu bakterije, ki je tankostenski valj, bomo izvedli izračun deformacij z upoštevanjem transverzalne anizotropičnosti bakterijske stene in hiperelastičnosti materiala stene. Najprej bomo izračun izvedli numerično za dva hiperelastična materialna modela, potem pa bomo izračun nadgradili s FEM-analizo. Pri analizi rezultatov obeh metod izračuna bomo ugotovili, da med obema rezultatoma pride do odstopanja, ki pa izhaja iz specificiranih predpostavk. In this thesis, we will investigate the response of a spherocylindrical bacterium to hydrostatic pressure. Using a simplified model of the bacterium, represented as a thin-walled cylinder, we will calculate the deformations, considering the transverse anisotropy of the bacterial wall and the hyperelasticity of the wall material. First, we will numerically perform the calculations for two hyperelastic material models, followed by an enhancement of the analysis using the Finite Element Method (FEM). Upon comparing the results from both calculation methods, we will identify discrepancies, which stem from the underlying assumptions specified in each approach. transverzalna anizotropija sferocilinder hiperelastičnost neo-hookov model holzapfel-gasser-ogdenov model transversal anisotropy spherocylinder hyperelasticity neo-hooke model holzapfel-gasser-ogden model true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2024-10-25 08:30:39 2024-10-25 08:30:42 2024-12-13 10:31:46 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 539.3:532.1:519.6(043.2) 267007 218949379 38312.pdf 38312.pdf 1 34F98CEC0E6D629805410DF5D60DE87B 0b5a9dba275700533d68f521aa0788d055d7c7bd1bd3f33aaff4ef078ceacd0f 5ec7a5c7-929a-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=194800 Fakulteta za strojništvo 0 0 0
