20.500.12556/RUL-173710 Numerični model za napoved gubanja toroidnih lupin z mehkimi jedri Numerical model for predicting wrinkling of toroidal shells with soft cores V nalogi je obravnavano gubanje toroidnih lupin z mehkimi jedri. Na osnovi teorije tankih lupin in Winklerjevega modela je bila zapisana energija sistema ter s Fourierjevimi vrstami predstavljena v numerični obliki. Z optimizacijo v Pythonu so bili iskani energijski minimumi in spremljan nastanek gubanja pri različnih obremenitvah. Rezultati pokažejo različne načine gubanja ter vpliv geometrije in togosti materiala na obliko deformacij. The thesis deals with the wrinkling of toroidal shells with soft cores. Based on thin shell theory and the Winkler model, the system energy was derived and expressed numerically using Fourier series. Optimization in Python was used to search for energy minima and to observe wrinkling under different loads. The results show different wrinkling modes and the influence of geometry and material stiffness on deformation shapes. torus lupine toroidne lupine gubanje mehka jedra numerični modeli Fourierjeva analiza optimizacija energije torus shells toroidal shells wrinkling soft cores numerical models Fourier analysis energy optimization true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2025-09-20 08:30:33 2025-09-20 08:30:34 2025-12-10 11:36:42 0000-00-00 00:00:00 2025 0 0 IX, 37 f. 2025 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2026-09-19 539.387:624.074.4:517.443(043.2) 276689 250245379 44779.pdf 44779.pdf 1 B7A30EA1AC56049A3ED66FBD17C54B19 0b34317f9857c400dd6934f9d6a285b9206d3b4c52750f342091aafd5f5f621a 24138e17-95eb-11f0-9328-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=218360 Fakulteta za strojništvo 0 0 0
