20.500.12556/DKUM-91181 A study on the compressive behavior of additively manufactured AlSi10Mg lattice structures The mechanical behavior of the metallic components fabricated by additive manufacturing (AM) technologies can be influenced by adjustments in their microstructure or by using specially engineered geometries. Manipulating the topological features of the component, such as incorporating unit cells, enables the production of lighter metamaterials, such as lattice structures. This study investigates the mechanical behavior of lattice structures created from AlSi10Mg, which were produced using the laser beam powder bed fusion (LB-PBF) process. Specifically, their behavior under pure compressive loading has been numerically and experimentally investigated using ten different configurations. Experimental methods and finite element analysis (FEA) were used to investigate the behavior of body-centered cubic (BCC) lattice structures, specifically examining the effects of tapering the struts by varying their diameters at the endpoints (dend) and midpoints (dmid), as well as altering the height of the joint nodes (h). The unit cells were designed with varying parameters in such a way that dend is changed at three levels, while dmid and h are changed at two levels. Significant differences in Young’s modulus, yield strength, and ultimate compressive strength between the various specimen configurations were observed both experimentally and numerically. The FEA underestimated the Young’s modulus corresponding to the configurations with thinner struts in comparison to the higher values found experimentally. Conversely, the FEA overestimated the Young’s modulus of those configurations with larger strut diameters with respect to the experimentally determined values. Additionally, the proposed FE method consistently underestimated the yield strength relative to the experimental values, with notable discrepancies in specific configurations. lattice structure BCC compressive behavior additive manufacturing AlSi10Mg struktura mreže stiskanje obnašanje materiala dodajalne tehnologije true false true MDPI Angleški jezik Slovenski jezik https://www.mdpi.com/journal/materials © 2024 by the authors Članek v reviji 2024-11-25 13:54:29 2024-11-25 13:54:29 2026-01-16 03:12:16 0000-00-00 00:00:00 2024 0 0 20 str. iss. 21, [article no.] 5188 Vol. 17 Oct. 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2024-09-13 2024-10-22 2024-10-24 620.1:658.5 215553795 10.3390/ma17215188 1996-1944 materials-17-05188.pdf materials-17-05188.pdf 1 E0457DEFCEE22D12E04AB3B33D2DF73E 0dae6b7dc22dcad3a254c13e5738f2b795af6f94f72f7169a1a226f303f987da 9b7ae491-f1e6-11f0-9ca2-00155d580e02 https://dk.um.si/Dokument.php?lang=slv&id=202036 https://www.mdpi.com/1996-1944/17/21/5188 0 0157521d-ab2d-11ef-9357-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=186935 Fakulteta za strojništvo 0 0 0
