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 model is calibrated to predict failure in numerical simulations. The GTN model is used to predict failure of the lattice structures exhibiting...
