title: Computational study and experimental validation of porous structures fabricated by electron beam melting: a challenge to avoid stress shielding.
abstract: 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.
