Undulation of the honeycombs׳ plateau stress under impact and the dynamic enhancement—Theoretical analysis

The analytical expression of the detailed undulation of the plateau stress of the hexagonal honeycombs under the low-velocity and the middle-velocity crushing is deduced, which consists of the static term and the dynamic term. It is shown that the level of the honeycomb׳s stress significantly decreases with the increase of the cell-wall angle under both the low-velocity and the middle-velocity impacts, which is mainly attributed by the static...
