Original abstract
This paper deals with the prediction of the mechanical behaviour of lattice structures made by selective laser melting (SLM). The work was divided into two stages where the first was aimed on evaluation of the material model for finite element analysis (FEA) from proposed tensile test specimens. The second stage was using previously evaluated material model for more complex structures composed of periodical truss cells. It was found that the major issue was the real geometry of additively produced specimens. For evaluation, stress-strain diagrams were used. All manufactured parts were made of aluminium alloy AlSi10Mg.
