The numerical simulations were realized using the commercial finite-element software Abaqus. The mechanical properties of the joint were identified using the gradient-optimization method implemented in the OptiSLang software. The identification was performed by minimizing the difference between the force-displacement diagram obtained from the numerical analyses and from the experiments. The shapes of the specimen and the bonded joint were designed in accordance with joints commonly used in the machine industryGlavni cilj tega dela je oceniti uporabo spoja na osnovi kohezivnega stika površin med rotacijskimi deli. Numerične simulacije so bile izvršene z uporabo komercialne programske opreme končnih elementov Abaqus. Mehanske lastnosti spoja pa so bile ugotovljene z uporabo gradientne optimizacijske metode, uporabljene s programsko opremo OptiSLang. Ugotavljanje je bilo izvršeno z zmanjšanjem razlike med vrednostmi na diagramu sila-raztezek, dobljenem z numerično analizo, in preizkusi. Oblike vzorcev in spojev so bile izvedene skladno s spoji, ki se pogosto uporabljajo v strojništvuTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaInštitut za kovinske materiale in tehnologije
