Virtual testing of as‐designed additively manufactured lattice structures

Abstract: Lattice structures and their characterization are much discussed in current research. The complex manufacturing process of laser powder bed fusion with its repeated melting and remelting of metallic powder influences the resulting material properties. Within this contribution the influence of process parameters on the overall behaviour of lattice structure compression test specimens is inherently described within the material model which is derived from tensile tests of additively manufactured material test specimens. The simulation of the lattice structures is performed with an isotropic elastic‐plastic material model on the as‐designed geometry, neglecting all geometric deviations caused by the manufacturing process. The comparison to compression experiments on the same, additively manufactured geometry, shows surprisingly good agreement. The potential of this approach is evaluated on compression tests with as‐built test specimens as well as test specimens which were heat treated after manufacturing.
