The paper describes computational modelling of regular closed-cell cellular materials behaviour when subjected to impact loading conditions. Parametric computational simulations have been carried out to evaluate influences of the relative density, strain rate, pore gas and gas type on the macroscopic dynamic behaviour of cellular materials. The behaviour of the model under uniaxial impact loading conditions and large deformations has been analysed with the LS-DYNA code, which is based on the finite element method. This study helps to clarify which effects are indeed important and would have to be considered in developing new homogenised constitutive relationships for analysing impact problems with use of general computational codes. Additionally, the detailed computational models provide an insight into behaviour of cellular material accounting for pore filler and basic constitutive relations for further development of homogenised models under impact conditions and large deformations. Furthermore, they allow for determination of most appropriate geometrical and material parameters of cellular materials in regard to individual engineering application demands.
