The introduction of additive manufacturing technologies allowed the production of lattice structure with different types of repeated unit cells. Lattice structures offer a significant structural mass reduction and can highly improve mechanical specific properties which are traits that are sought in sectors like aerospace and automotive. In this thesis six types of unit cells (BCC, BCCZ, FCC, FCCZ, FBCC and FBCCZ) are analyzed through static simulations under compression and shear using ANSYS Workbench. The material is AlSi10Mg, one of the most used metal in additive manufacturing. The aim of this work is to create a model that can predict the mechanical properties of structures with different geometrical parameters through the simulation’s results of unit cells with four aspect ratios.
