20.500.12556/DKUM-82278 Parametrične simulacije tlačnega obnašanja tri-periodičnih metamaterialov proizvedenih z dodajalnimi tehnologijami magistrsko delo Parametric simulations of compressive behaviour of triply periodic metamaterials manufactured with additive technologies V magistrskem delu je predstavljen inverzen postopek razvoja materialnega modela, ki upošteva napake v tri-periodični minimalni površinski (TPMS) celični strukturi proizvedeni z dodajalnimi tehnologiji. TPMS celične strukture na osnovi plošč so novi metamateriali, ki kažejo visok potencial v širokem spektru uporabe. Pridobljeni, urejeni in ovrednoteni so bili eksperimentalni rezultati tlačnega preizkušanja TPMS celične strukture iz nerjavečega jekla AISI 316L. Izvedene so bile kvazi-statične računalniške simulacije s programskim paketom LS-Dyna na računalniški gruči Univerze v Mariboru HPC-CORE. Cilj simulacij je bil izdelati materialni model s katerim bi dobro ujeli eksperimentalne rezultate preizkušancev. Preizkušenih je bilo več načinov upoštevanja napak v strukturi in ovrednoten je bil vpliv porazdelitve napak po strukturi. Pridobljeni rezultati simulacije so pokazali dobro ujemanje z eksperimentalnimi rezultati. The master thesis presents an inverse material model development procedure that takes into account the defects in the triply-periodic minimal surface (TPMS) cellular structure produced by additive manufacturing. TPMS cellular structures based on shells are new metamaterials showing high potential in a wide range of applications. Experimental results of compression testing of TPMS cellular structures made from AISI 316L stainless steel were obtained, collected, and evaluated. Quasi-static computer simulations were performed with the LS-Dyna software package on the University of Maribor HPC-CORE computer cluster. The aim of the simulations was to determine a material model that would give results as close as possible to the experimental results. Several approaches for accounting of errors in the structure were tested and the influence of error distribution across the structure was evaluated. The simulation results obtained showed a good corelation with the experimental results. metoda končnih elementov kvazi-statične simulacije celični materiali tri-periodične minimalne površine dodajalne tehnologije finite element method quasi-static simulations cellular materials triply periodic minimal surface additive technologies true true false [K.
