Summary: | Abstract
The main factors affecting honeycomb in-plane deformation modes are researched using Patran/LS-DYNA in this paper. All changes in deformation modes can be summarized as changes in constraints. The main factors affecting the deformation modes include the material constitutive models, the boundary constraints, the cell wall thickness-to-length ratio
h/l
and the aspect ratio of honeycomb. Inner cells’ constraints and shape of crush bands are affected by the material constitutive models. The sliding difficulty of boundary cells and the initiation of crush bands are influenced by the boundary constraints especially the horizontal frictions and the cell wall thickness-to-length ratio

. The number and region of crush bands are affected by the aspect ratio. |
