Effects of Cell-wall Angle on the Mechanical Properties of Hexagonal Honeycombs

摘要

The y-directional mechanical properties of hexagonal honeycombs with various cell-wall angles ar; explored. The results of both the quasi-static experiments and the dynamic simulations show thai: the cell-wall angle has a significant influence on the honeycombs' mechanical properties, although the latter is dominated by the honeycombs' relative density. This influence is weakened by the increase of the impact velocity. With retaining the honeycombs' relative density as constant, the honeycomb with the cell-wall angle of about 45° exhibits the optimal crushing strength and energy absorption capacity.
