20.500.12556/RUL-166869 The Impact of the geometry of cellular structure made of glass-filled polyamide on the energy-absorbing properties of design elements Energy-absorbing properties of cellular materials with D, G, IWP*, N, P, Q, PJ triply minimal energy surface geometries were investigated. Materials were made of glass-filled polyamide by selective laser sintering. Mechanical properties of cellular structures were determined depending on the geometry: the highest specific compressive strength σsp.max >8 MPa∙cm3/g is possessed by samples with the geometry IWP* and PJ; the highest specific energy absorption Asp = 14.5 MJ/m3 is in the sample with the geometry N. A mass-strength criterion for cellular structures is proposed. The maximal values of mass-strength criterion are from samples with geometries N, IWP* and PJ; 4.16 MPa2/g, 3.51 MPa2/g, and 2.88 MPa2/g. The adequacy of applying the Gibson-Ashby equation for fabricated cellular materials with triply periodic minimal surfaces (TPMS) geometry has been proven. additive technologies selective laser sintering polyamide glass triply periodic minimal surface energy absorption dampers dodajalne tehnologije selektivno lasersko sintranje poliamid steklo trojno periodična minimalna površina absobcija energije blažilniki true false false Angleški jezik Slovenski jezik Neznano 2025-01-28 12:12:29 2025-01-28 12:12:33 2025-01-29 03:57:06 0000-00-00 00:00:00 2024 0 0 Str. 595-606 no. 11/12 Vol. 70 2024 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 2024-03-09 2024-06-18 2024-12-01 621 2536-3948 10.5545/sv-jme.2024.975 224218115 RAZ_Diachenko_Semen_V._2024.pdf RAZ_Diachenko_Semen_V._2024.pdf 1 D1DEDB5E99D8C2ED361CBE3C0EC8D88A 2772d2c84fbfd87adf06247289fecb512f3aea037c43fe26442cd6082873aee4 7b59228e-dd68-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=198832 https://www.sv-jme.eu/sl/article/impact-of-the-geometry-of-cellular-structure-of-glass-filled-polyamide-material-on-the-energy-absorbing-properties-of-design-elements/ 1 f7579429-dd67-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=198831 Fakulteta za strojništvo Strojniški vestnik 0 0 0
