The work aims to study the influence of cell wall material properties on the in-plane compressive mechanical property of aluminum honeycomb. With the structural parameter of regular hexagonal honeycomb unchanged, the cell wall material property was changed, the cell wall material models respectively selected the bilinear isotropic hardening model and ideal elastic-plastic model with different strain hardening parameters, the relevant reliable finite element model was established and a lot of simulation computation was done. The corresponding deformation mode and stress-strain curves were obtained to further process the curves, so as to obtain the honeycomb in-plane static and dynamic peak stresses. Moreover, the results were displayed and analyzed in a graphical form. These results showed that three kinds of deformation modes, such as the "X"-shaped, "V"-shaped and "I"-shaped samples were observed with the increasing impact velocities. The strain hardening effect of cell wall material made the deformation tend to be homogeneous and significantly increased the static peak stress of honeycomb, but the impact of dynamic peak stress increment could be ignored. The calculation formula of strain hardening parameter and dynamic peak stress was derived after the calculating data were processed. The honeycomb with hardening properties of cell wall material has better in-plane static mechanical properties than that with the perfectly elastoplastic material model of cell wall material. For the use of numerical simulation method to study the in-plane static mechanical behavior of honeycomb structure, the hardening effect of cell wall material needs to be considered.
