Abstract

Abstract: In most previously constructed lattice inspired structures, atoms were not included. Thus, their mechanical behaviours might not well simulate the lattice structures. In the present work, a body-centred cubic (BCC) inspired structure with atoms as reinforced nodes and atomic bonds as connected struts, was additively manufactured using Ti-6Al-4V alloy via a selective laser melting. Results of mechanical compression test and finite element analysis revealed the higher yield strength, collapse strength and energy absorption capability of the BCC-inspired structure with reinforced nodes than the ones without reinforcement.
