20.500.12556/DKUM-96493 The pitfalls of reverse engineering topology optimised load-carrying structural parts into parametric models In this paper, we will show the topological optimization of a load-carrying structural parts and the errors that can occur when the topological solution in the form of a triangulated mesh of the surface of the optimized part is reconstructed into a parametric CAD form. Such a reconstruction always introduces geometric errors in the resulting optimal structure of the structural element. A numerical example will be used to show how quickly stress concentrations are reproduced on surfaces where they should not be. The numerical results are also supported by experiment. In the conclusion, it is suggested how, with a specific topological model, the obtained stress concentrations at the edges of the structure can be reduced. load-carrying structural parts reverse engineering stress concentrations topology optimisation konstrukcijski deli za obremenitev povratni inženiring koncentracije stresa topologija optimizacija true false true Sveučilište Sjever Angleški jezik Slovenski jezik http://tehnickiglasnik.unin.hr/ Članek v reviji 2026-01-14 12:28:05 2026-01-14 12:28:05 2026-01-15 03:10:12 0000-00-00 00:00:00 2024 0 0 str. 204-208 no. 2 Vol. 18 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-08-21 2023-09-27 2024-05-31 539.4 203806723 10.31803/tg-20230821142854 1848-5588 tj_18_2024_2_204-208.pdf tj_18_2024_2_204-208.pdf 1 DB7E5E951A193D9216E73CA8F9EEED43 952cd11a7384cfe6b80fcaac67dc367ceafddccdb855724a1679206113bd6614 85c26297-f13c-11f0-8a93-00155d580e02 https://dk.um.si/Dokument.php?lang=slv&id=202001 https://hrcak.srce.hr/316901 0 9c3fbf01-f13c-11f0-8a93-00155d580e02 https://dk.um.si/Dokument.php?lang=slv&id=202002 Fakulteta za strojništvo 0 0 0
