Abstract:Diplomska naloga obravnava uporabo virtualnega prototipiranja pri analizi mehanskih lastnosti 3D natisnjenih polimernih materialov. Predstavljen je pomen virtualnega prototipiranja za skrajšanje časa in stroškov razvoja ter njegova uporaba pri preverjanju mehanskega obnašanja PLA in PLA+CF, izdelanega s FDM postopkom. Eksperimentalni del temelji na nateznih preizkusih standardiziranih preizkušancev, numerični pa na simulacijah v programu ANSYS Workbench z eksplicitno dinamiko z Johnson-Cook modelom. Model je bil obravnavan kot homogeno polno telo brez notranjih struktur, pri čemer je bila stabilnost simulacij preverjena z energijskimi kriteriji. Rezultati kažejo dobro ujemanje pri modulu elastičnosti in raztezku, medtem ko so pri natezni trdnosti opazna za malenkost večja odstopanja. Naloga potrjuje, da virtualno prototipiranje omogoča zanesljivo napoved osnovnih mehanskih lastnosti PLA in ima velik potencial kot dopolnitev klasičnim eksperimentalnim pristopom.

Title:VIRTUAL PROTOTYPING IN THE PRODUCT DESIGN AND ANALYSIS PROCESS
Abstract:This thesis addresses the use of virtual prototyping in the analysis of mechanical properties of 3D-printed polymer materials. It presents the importance of virtual prototyping for reducing development time and costs, as well as its application in evaluating the mechanical behavior of PLA and PLA reinforced with carbon fibers (PLA+CF), manufactured using the FDM process. The experimental part is based on tensile tests of standardized specimens, while the numerical part is based on simulations performed in ANSYS using Explicit Dynamics with the Johnson-Cook material model. The model was treated as a homogeneous solid body without internal structures, and the stability of the simulations was verified using energy criteria. The results show good agreement in terms of elastic modulus and strain, while slightly larger deviations are observed in tensile strength. The thesis confirms that virtual prototyping enables reliable prediction of the basic mechanical properties of PLA and has significant potential as a complement to classical experimental approaches.
