In the first problem the plasticity of material was considered, and in the second, also- the possibility of spokes buckling. Conclusions about the efficiency of use of steel and aluminium in loaded elements of thinwalled structures are madeDvoslojni obroč različne debeline iz jekla in kolo z jeklenim obročem in z jeklenimi ali aluminijastimi špicami sta bila analizirana po metodi FEM. V prvem primeru je bila upoštevana plastičnost materiala in v drugem tudi uklon špic. Oblikovani so zaključki o učinkovitosti uporabe jekla in aluminija v obremenjenih tankostenih strukturahNadaljuje se kot: Materiali in tehnologijeTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
