Virtual testing of as‐designed additively manufactured lattice structures

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