Abstract :

[en] Abstract. With additive manufacturing, innovative porous structures emerge for generating lightweight components with high mechanical responses. Body-centered cubic lattice structures are the focus of this study, with customizable lattice density depending on the strut diameter. To predict the properties of lattice structures and thus reduce the number of tests in experimental campaigns, several numerical and analytical models have been developed. In this work, the elastoplastic response was determined. Buckling phenomena of vertical struts depend on the different boundary conditions applied in Finite Element simulations. As shown the number of cells within the model affects the results. This size effect was quantified for different lattice density cases. The numerical results obtained for lattice structures with different relative density were also compared with the well-known Gibson-Ashby model.
