Abstract:V diplomskem delu so obravnavane različne vrste geometrij štirikiralnih avksetičnih struktur preizkušancev iz materialov PLA in TPU, ki so bile eksperimentalno karakterizirane in računalniško simulirane. S programom SolidWorks so bile parametrično modelirane tri različne geometrije, pri katerih se je spreminjala vrednost amplitude in debeline celične stene. Preizkušanci so bili nato narejeni z uporabo dodajalnih tehnologij. Izvedeni so bili enoosni natezni preizkusi in nato računalniške simulacije, pri katerih se je želelo približati eksperimentalnim rezultatom. Geometrija tri je pri obeh materialih dosegla največjo povprečno maksimalno natezno silo. Geometrija ena se je pri obeh materialih v smeri obremenitve povprečno raztegnila za največ.

Title:Experimental Characterisation and Development of the Computational Model of Tetrachiral Auxetic Structure
Abstract:In the thesis, different types of geometries of tetrachiral auxetic structures made of PLA and TPU materials, which were experimentally characterised and computer simulated, are discussed. Three different geometries were parametrically modelled in SolidWorks, varying the amplitude and thickness of the cell wall. Test specimens were then made using additive technologies. Uniaxial tensile tests and later computer simulations were carried out with intent to approach the experimental results. Geometry three achieved the highest average maximum tensile force for both materials. Geometry one stretched the most on average in the direction of tensile loading for both materials.
Keywords:auxetic structures, parametric modeling, additive technologies, tensile test, computer simulations
