20.500.12556/RUL-143647 Numerical modeling based on finite element analysis of 3d-printed wood-polylactic acid composites a comparison with experimental data Wood-polymer composites are increasingly produced through fused deposition modeling (FDM)—an additive manufacturing technique. The versatility of this technology has attracted several industries to print complex shapes and structures. This underscores the importance of studying the mechanical properties of the FDM parts, specifically, their elastic properties. A numerical homogenization methodology is introduced in the present study, focusing on the fundamental aspect of the elastic properties. Investigations were carried out on the influence of various parameters like wood volume fraction, aspect ratio, and internal porosity. The numerical results were validated using analytical models and experimental data. The comparison showed a satisfactory agreement with experimental data, where the relative error did not exceed 10%, leading to a strong conclusion about the validity and effectiveness of the proposed approach. wood Maillard reaction PLA 3D printing natural fiber composite homogenization elastic properties finite element analysis les 3 D tisk kompoziti termična modifikacija homogenizacija elastičnost analiza končnih elementov true false false Angleški jezik Slovenski jezik Neznano 2023-01-05 09:58:55 2023-01-05 09:59:00 2023-01-06 03:34:05 0000-00-00 00:00:00 2023 0 0 1 spletni vir (1 datoteka PDF (17 str.)) iss. 1 Vol. 14 2023 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 2023-01-01 630*8 1999-4907 10.3390/f14010095 136279555 https://www.mdpi.com/1999-4907/14/1/95 1 fad4a009-8cd6-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=165481 RAZ_Ezzaraa_Ismail_2023.pdf RAZ_Ezzaraa_Ismail_2023.pdf 1 E3F420D2B01BCE84049F665BDF310B88 892dadc2f9ecf60c2e29d90ad886a8b95d04ec2c3853ee4ff08c02d55208f0d1 224a5a8f-8cd8-11ed-9c94-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=165482 Biotehniška fakulteta 0 0 0
