Desing Of A Lattice-Core Sandwich Panel For Additive Manufacturing

Abstract

In the present work, the finite element analysis (FEA) of AlSi10Mg body-centered-cubic lattice-core sandwiches manufactured by laser powder bed fusion additive manufacturing technique were performed using solid, beam and homogenized solid and shell models. Vibration experiments were performed for three different additively manufactured lattice sandwich specimens. The natural frequencies of the modal FEA showed good agreements with those of the experiments. It was further shown that the beam element model was the most efficient modeling method for both static and modal FEA by considering the computational cost.
