Effect of cell-wall angle on the in-plane crushing behaviour of hexagonal honeycombs

The dynamic crushing behaviors in the x- and the y-directions of hexagonal honeycombs with various cell-wall angles are explored by both experiments and numerical simulations. Several deformation modes are identified based on the shape of the localization band forming by the cells’ collapse. The respective influence of the cell-wall angle, the crushing velocity and the honeycomb’s relative density on the honeycomb’s mechanical properties is...
