The in-plane static and impact compression phenomena of aluminum honeycombs were experimentally investigated. Particularly, the effect of srtain rate on the deformation of honeycomb was studied. Also, by defining a "cell-scale strain" and a "macro-scale strain" in the present paper, the relationship between them in the deformation process of individual cells and that of the entire honeycomb was investigated. As a result, it was found that the strain rate affected the position of a localized condensation and the plastic collapse mode of cells and the cell-scale strain and macroscale strain showed different behaviors in the honeycombs. Moreover, the critical impact velocity for the transition of collapse modes was estimated.
