Computational study and experimental validation of porous structures fabricated by electron beam melting: A challenge to avoid stress shielding

• Diamond non-stochastic lattice structures were fabricated by electron beam melting.
• Finite element models of the structures were developed.
• An inverse relationship between aspect ratio and elastic modulus it is shown.
• An equation that estimates the elastic modulus of the structure was obtained.
• Differences between the numerical and the experimental results were discussed.

In this paper, several diamond non-stochastic lattice structures, fabricated by electron beam melting, were mechanically characterized by compression tests. A finite element model of the structures was developed, obtaining an equation that estimates the elastic modulus of the lattice structure. Finally, the differences between the numerical and the experimental results were analyzed and discussed.
