Abstract: Cellular structures have an attractive combination of mechanical properties and are increasingly used in modern engineering applications. Consequently, the research of their behaviour under quasi-static and dynamic loading is valuable for engineering applications such as those related to strain energy absorption. The paper focuses on behaviour of a newly developed cellular structure UniPore with unidirectional pores under dynamic loading. The computational model of the cellular structure was based on realistic (reconstructed) irregular geometry of the manufactured specimens and analysed using the code LS-DYNA. The mechanical properties have been investigated by means of parametric computational simulations considering various material and geometrical parameters. Additionally, the influence of the gaseous pore filler influence has been considered using fully coupled computational models. Furthermore, with computational simulations also the influence of the anisotropy has been evaluated.
