Multiaxial static strength of a 3D printed metallic lattice structure exhibiting brittle behavior

This paper focuses on numerical the prediction of multiaxial static strength of lattice structures. We analyze a body‐centered cubic cell printed with Selective Laser Melting in AlSi10Mg aluminum alloy. Parent material is experimentally characterized, and the Gurson‐Tveergard‐Needleman (GTN) damage...
