20.500.12556/RUL-155548 Thermoelasticity of injection-molded parts In the realm of injection-molded parts, small length scale deformation defects such as sink marks often pose a major challenge to the aesthetics or functionality of the parts. To address this problem, we present a comprehensive thermoelastomechanical approach that calculates the deformation of injection molded plastic by solving the elastic problem at each time step. In our methodology, two treatments of the molten core are considered: one as a liquid and the other as a rubbery state. Our results suggest that the rubbery state treatment provides higher accuracy in predicting the deformation results, as it maintains the displacement of the localized thermal shrinkage in its vicinity. The validity of our method is supported by empirical measurements on produced parts from the existing literature as well as on samples that we molded independently. thermoelasticity injection molding plastic deformations sink mark volumetric shrinkage injection molding defect termoelastičnost injekcijsko brizganje plastika deformacije true false true Angleški jezik Slovenski jezik Članek v reviji 2024-04-05 13:08:55 2024-04-05 13:08:56 2024-12-11 10:02:15 0000-00-00 00:00:00 2023 0 0 22 str. iss. 13, art. 2841 Vol. 15 2023 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 621.767 2073-4360 10.3390/polym15132841 157351939 Clanek_Svensek.pdf Clanek_Svensek.pdf 1 6F1C6B02193174D970CC79B051391DDF 3a8d21ac1ff4b46e28917e986961897d03b1e4fd1a35cb7ba7643c6db8792ef9 11bf1d87-f33d-11ee-afc9-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182505 https://www.mdpi.com/2073-4360/15/13/2841 0 1824840f-f33d-11ee-afc9-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182506 Fakulteta za matematiko in fiziko 0 0 0
