Popis: Cellular materials fabricated with metal powder micromelting can be used to mimic biological structures with optimized strength/mass ratios. The validation of predictive models requires specific parametric laboratory tests and additive processes with high stability and repeatability. The evaluation of equivalent properties of lattice structures able to compare the behavior of bulk materials is of paramount importance for the designer. At this purpose, dedicated modeling methods as the homogenization are needed. This paper introduces the results of metal lattice structures characterization under quasi-static compressive load with parametric variation of cells dimensions. The failure mechanisms are also described in view of applications in energy absorption.
