Study of the static and dynamic behavior of lattice structures made by additive manufacturing filled with polymers. The activity involves the creation of 3D CAD models of metallic cellular structures based on the characteristics of laboratory specimens. The metallic structures, made with AM, are filled with polymers with variable hardness (shoreA 30-60). Following, FEM numerical simulation are performed about the static compression behaviour of the samples and comparison with experimental results. When calibration of the static model is obtained, the analysis of the dynamic behavior of the sample itself is provided (modal and harmonic analysis). The same are repeated for a functional component.
